+How Do I Do If the Spark Job Error "UnknownScannerExeception" Is Reported?
+==========================================================================
+
+Symptom
+-------
+
+Spark jobs run slowly. Warning information is printed in run logs, and the error cause is **UnknownScannerExeception**.
+
+Solution
+--------
+
+Before running a Spark job, adjust the value of **hbase.client.scanner.timeout.period** (for example, from 60 seconds to 120 seconds).
+
+Log in to FusionInsight Manager and choose **Cluster** > **Services** > **HBase**. Click **Configurations** then **All Configurations**, search for **hbase.client.scanner.timeout.period**, and change its value to **120000** (unit: ms).

+How Do I View MRS Job Logs?
+===========================
+
+#. .. _mrs_03_1172__li943507288:
+
+   On the **Jobs** page of the MRS console, you can view logs of each job, including launcherJob and realJob logs.
+
+   -  Generally, error logs are printed in **stderr** and **stdout** for launcherJob jobs, as shown in the following figure:
+
+      |image1|
+
+   -  You can view realJob logs on the ResourceManager web UI provided by the Yarn service on MRS Manager.
+
+      |image2|
+
+#. Log in to the Master node of the cluster to obtain the job log files in :ref:`1 <mrs_03_1172__li943507288>`. The HDFS path is **/tmp/logs/**\ *{submit_user}*\ **/logs/**\ *{application_id}*.
+
+#. After the job is submitted, if the job application ID cannot be found on the Yarn web UI, the job fails to be submitted. You can log in to the active Master node of the cluster and view the job submission process log **/var/log/executor/logs/exe.log**.

-ALM-12012 NTP Service Is Abnormal
-=================================
-
-Description
------------
-
-The system checks whether the NTP service on a node synchronizes time with the NTP service on the active OMS node every 60 seconds. This alarm is generated when the NTP service fails to synchronize time for two consecutive times.
-
-This alarm is generated when the time difference between the NTP service on a node and the NTP service on the active OMS node is greater than or equal to 20s for two consecutive times. This alarm is cleared when the time difference is less than 20s.

-
-Impact on the System
---------------------
-
-The time on the node is inconsistent with that on other nodes in the cluster. Therefore, some FusionInsight applications on the node may not run properly.
-
-Possible Causes
----------------
-
--  The NTP service on the current node cannot start properly.
--  The current node fails to synchronize time with the NTP service on the active OMS node.
--  The key value authenticated by the NTP service on the current node is inconsistent with that on the active OMS node.
--  The time offset between the node and the NTP service on the active OMS node is large.

-Procedure
----------
-
-**Check the NTP service mode of the node.**
-
-#. .. _alm-12012__li24978126120:
-
-   Log in to the active management node as user **root**, run the **su - omm** command to switch to user **omm**, and run the following command to check the resource status on the active and standby nodes:
-
-   **sh ${BIGDATA_HOME}/om-server/om/sbin/status-oms.sh**
-
-   -  If "chrony" is displayed in the **ResName** column of the command output, go to :ref:`2 <alm-12012__li565253915220>`.
-   -  If "ntp" is displayed in the **ResName** column, go to :ref:`20 <alm-12012__li18137932125120>`.
-
-   .. note::
-
-      If both "chrony" and "ntp" are displayed in the **ResName** column of the command output, the NTP service mode is being switched. Wait for 10 minutes and go to :ref:`1 <alm-12012__li24978126120>` again. If both "chrony" and "ntp" persist, contact O&M personnel personnel.
-
-**Check whether the chrony service on the node is started properly.**
-
-2. .. _alm-12012__li565253915220:
-
-   On FusionInsight Manager, choose **O&M** > **Alarm** > **Alarms**. On the page that is displayed, click |image1| in the row containing the alarm, and view the name of the host for which the alarm is generated in **Location**.
-
-3. Check whether the chronyd process is running on the node where the alarm is generated. Log in to the node for which the alarm is generated as user **root** and run the **ps -ef \| grep** **chronyd \| grep -v grep** command to check whether the command output contains the chronyd process.
-
-   -  If yes, go to :ref:`6 <alm-12012__li128001354104320>`.
-   -  If no, go to :ref:`4 <alm-12012__li112931223172310>`.

-
-   Run the **systemctl chronyd start** command to start the NTP service. (Currently, only CentOS and Red Hat Enterprise Linux 7.0 or later are supported.)
-
-5. Check whether the alarm is cleared 10 minutes later.
-
-   -  If yes, no further action is required.
-   -  If no, go to :ref:`6 <alm-12012__li128001354104320>`.

-
-Impact on the System
---------------------
-
-The NTP server configured on the active OMS node is abnormal. In this case, the active OMS node cannot synchronize time with the NTP server and a time offset may be generated in the cluster.
-
-Possible Causes
----------------
-
--  The NTP server network is abnormal.
--  The NTP server authentication fails.
--  The NTP server time cannot be obtained.
--  The time obtained from the NTP server is not continuously updated.

-ALM-12103 Executor Resource Exception
-=====================================
-
-Description
------------
-
-HA checks the Executor resources of Manager every 30 seconds. This alarm is generated when HA detects that the Executor resources are abnormal for two consecutive times.
-
-This alarm is cleared when the Executor resources are normal.
-
-**Resource Type** of Executor is **Single-active**. Active/standby will be triggered upon resource exceptions. When this alarm is generated, the active/standby switchover is complete and new Executor resources have been enabled on the new active Manager. In this case, this alarm is cleared. This alarm is used to notify users of the cause of the active/standby Manager switchover.

-
--  The active/standby Manager switchover occurs.
--  The Executor process keeps restarting. As a result, the cluster page may fail to be accessed.
-
-Possible Causes
----------------
-
-The Executor process is abnormal.
-
-Procedure
----------
-
-**Check whether the Executor process is abnormal.**
-
-#. In the alarm list on FusionInsight Manager, locate the row that contains the alarm, and click |image1| to view the name of the host for which the alarm is generated.
-
-#. Log in to the host for which the alarm is generated as user **root**.
-
-#. Run the **su - omm** command to switch to user **omm**.
-
-#. Run the **sh ${BIGDATA_HOME}/om-server/OMS/workspace0/ha/module/hacom/script/status_ha.sh** command to check whether the status of the Executor resources managed by the HA is normal. In the single-node system, the Executor resource is in the normal state. In the dual-node system, the Executor resource is in the normal state on the active node and in the stopped state on the standby node.
-
-   -  If yes, go to :ref:`7 <alm-12103__li6152360163635>`.
-   -  If no, go to :ref:`5 <alm-12103__li139657016249>`.
-
-#. .. _alm-12103__li139657016249:
-
-   Run the **vi $BIGDATA_LOG_HOME/omm/oms/ha/scriptlog/executor.log** command to check whether the Executor resource log of HA contains the keyword **ERROR**. If yes, analyze the log to locate the resource exception cause and fix the exception.
-
-#. After 5 minutes, check whether this alarm is cleared.
-
-   -  If yes, no further action is required.
-   -  If no, go to :ref:`7 <alm-12103__li6152360163635>`.

----------
-
-#. On FusionInsight Manager, choose **O&M** > **Alarm** > **Alarms**. On the page that is displayed, click |image1| in the row containing the alarm and view the additional information of the alarm.
-#. Rectify the fault based on the following scenarios:
-
-   -  If "Call CES to send metrics fail. Permission exception" is displayed in the additional information, the token of the resource tenant is invalid. Restart the Controller and obtain the token again.
-   -  If "Call CES to send metrics fail. Request CES error code xxx" is displayed in the additional information, an error occurs in the request to Cloud Eye. Check the network connectivity and authentication information.
-   -  If "Call CES to send metrics fail. CES internal error code xxx" is displayed in the additional information, the Cloud Eye service encounters an internal error and is unavailable. Contact O&M personnel and send collected fault logs.

-=============================================================
-
-Description
------------
-
-The system checks the RegionServer handler usage of each HBase service instance every 30 seconds. This alarm is generated when the handler usage of a RegionServer exceeds the threshold (90% for five consecutive times by default). This alarm is cleared if the handler usage is lower than or equal to the threshold.

-Impact on the System
---------------------
-
-The heap memory overflow may cause a service breakdown.
-
-Possible Causes
----------------
-
-The heap memory of the Loader instance is overused or the heap memory is inappropriately allocated.
-
-Procedure
----------
-
-**Check heap memory usage.**
-
-#. On the FusionInsight Manager portal, choose **O&M** > **Alarm** > **Alarms** > **Loader Heap Memory Usage Exceeds the Threshold** > **Location.** Check the host name of the instance involved in this alarm.
-
-#. On the FusionInsight Manager portal, choose **Cluster** > *Name of the desired cluster* > **Services** > **Loader** > **Instance**. Click the instance for which the alarm is generated to go to the page for the instance. Click the drop-down menu in the chart area and choose **Customize** > **Memory** > **Loader Heap Memory Resource Percentage**. Click **OK**.
-
-#. Check whether the used heap memory of Loader reaches the threshold (the default value is 95% of the maximum heap memory) specified for Loader.
-
-   -  If yes, go to :ref:`4 <alm-23004__en-us_topic_0070543528_d0e41794>`.
-   -  If no, go to :ref:`6 <alm-23004__en-us_topic_0070543528_d0e41845>`.

-
-   On the FusionInsight Manager portal, choose **Cluster** > *Name of the desired cluster* > **Services** > **Loader** > **Configurations**. Click **All Configurations**. Increase the value of **-Xmx** in **GC_OPTS** as required, and click **Save**. Click **OK**.
-
-   .. note::
-
-      -  If this alarm is generated, the heap memory configured for the current Loader instance is insufficient for data transmission. You are advised to open the instance monitoring page, display the Loader heap memory resource status monitoring chart, and observe the change trend of the heap memory used by Loader in the monitoring chart. Then change the value of **-Xmx** to twice the current heap memory usage or to another value to meet site requirements.
-      -  When setting the heap memory, you can set **-Xms** and **-Xmx** to similar values to avoid performance deterioration caused by heap size adjustment after each GC.
-      -  Ensure that the sum of **-Xmx** and **XX:MaxPermSize** is not greater than the physical memory of the node server.
-
-#. Restart the affected services or instances and check whether the alarm is cleared.
-
-   -  If yes, no further action is required.

-
-The system checks the non-heap memory usage of the Loader service every 30 seconds. The alarm is generated when the non-heap memory usage of a Loader instance exceeds the threshold (80% of the maximum memory) for 5 consecutive times. The alarm is cleared when the non-heap memory usage is less than the threshold.

-ALM-38011 User Connection Usage on Broker Exceeds the Threshold
-===============================================================
-
-Description
------------
-
-The system checks the number of connections of each user on Broker every 30 seconds. This alarm is generated when the connection usage of a user on the Broker exceeds the threshold (80% by default) for 5 consecutive times.
-
-The number of times that smoothing is performed is **5**. This alarm is cleared when the connection usage of a user on the Broker is less than the threshold.
-
-The alarm can be automatically cleared. However, if the number of connections of a user suddenly becomes **0** and no connection is created, the alarm cannot be automatically cleared. You need to manually clear it.

-Parameters
-----------
-
-=========== ========================================================
-Name        Meaning
-=========== ========================================================
-Source      Specifies the cluster for which the alarm is generated.
-ServiceName Specifies the service for which the alarm is generated.
-RoleName    Specifies the role for which the alarm is generated.
-HostName    Specifies the host for which the alarm is generated.
-UserName    Specifies the username for which the alarm is generated.
-=========== ========================================================
-
-Impact on the System
---------------------
-
-If the number of connections of a user is excessive, the user cannot create new connections to the Broker.
-
-Possible Causes
----------------
-
--  The number of connections (created by a user) used by the client exceeds the preset threshold.
--  The threshold for the connection usage does not meet service requirements.
-
-Procedure
----------
-
-**Check the number of connections established by the same user on the client.**
-
-#. On the FusionInsight Manager home page, choose **O&M** > **Alarm** > **Alarms** > **User Connection Usage on Broker Exceeds the Threshold**. Check the host name and username of the Broker instance for which the alarm is generated in **Location**.
-
-#. .. _alm-38011__li19192924516:
-
-   On FusionInsight Manager home page, choose **Cluster** > *Name of the desired cluster* > **Services** > **Kafka** > **Instance**. Click the instance for which the alarm is generated to go to the page for the instance. Click the drop-down list in the upper right corner of the chart area, choose **Customize > Other**, and select **User Connection Usage on Broker**, **Maximum Number of User Connections on Broker**, and **Number of User Connections on Broker** to view the number of the current user connections on the Broker.
-
-#. Observe the number of real-time connections of the current alarm user and check whether the real-time monitoring data of the current user exists.
-
-   -  If yes, go to :ref:`4 <alm-38011__li7238347142216>`.
-   -  If no, the current user has disconnected all connections. You need to clear the alarm manually, and no further action is required.
-
-      .. note::
-
-         After the alarm user disconnects all connections, the monitoring data of the user disappears. In this case, the alarm will not be automatically cleared. You need to manually clear it.
-
-#. .. _alm-38011__li7238347142216:
-
-   Check whether the user is authorized by the service side.
-
-   If yes, go to :ref:`7 <alm-38011__li767116237265>`.
-
-   If no, go to :ref:`5 <alm-38011__li10246106955>`.
-
-#. .. _alm-38011__li10246106955:
-
-   Run the following command on the client to limit the number of connections of the user. There are two configuration rules based on the following commands:
-
-   a. For the specific Broker and user, run the following command:
-
-      **kafka-configs.sh --bootstrap-server** *<broker ip:port>* **--alter --add-config 'max.connections.per.user.overrides=[**\ *<username>*\ **:**\ *<connection.number>*\ **]' --entity-type brokers --entity-name** *<broker.id>* **--command-config Kafka/kafka/config/producer.properties**
-
-      .. note::
-
-         For unauthorized users, confirm with the service side to reduce the maximum number of connections of an unauthorized user or set the maximum number of connections to **0**.
-
-         In the command, you need to specify the IP address and port number of Broker, set values of configuration items, and specify the **brokerId** and **username**. Here, the user refers to the authorized Kerberos user.
-
-         The configuration updated using the command line tool can take effect dynamically. The configuration becomes invalid after the service is restarted. To make the configuration take effect after the restart, choose **Cluster** > *Name of the desired cluster* > **Services** > **Kafka** > **Configurations** > **All** **Configurations**> **Broker** > **Server** on the FusionInsight Manager home page and update the configuration to **max.connections.per.user.overrides**.
-
-   b. For the specific use and default Broker (that is, all Broker instances in the cluster), run the following command:
-
-      **kafka-configs.sh --bootstrap-server** *<broker ip:port>* **--alter --add-config 'max.connections.per.user.overrides=[**\ *<username>*\ **:**\ *<connection.number>*\ **]' --entity-type brokers ---entity-default --command-config Kafka/kafka/config/client.properties**
-
-      Example:
-
-      **kafka-configs.sh --bootstrap-server 10.153.3.26:21007 --alter --add-config 'max.connections.per.user.overrides=[showcase:4]' --entity-type brokers --entity-name 1 --command-config Kafka/kafka/config/client.properties**
-
-#. Check whether the maximum number of connections is **0** and whether the number of connections of the current user decreases or remains unchanged according to :ref:`2 <alm-38011__li19192924516>`.
-
-   -  If yes, manually clear the alarm and no further action is required.
-   -  If no, go to :ref:`7 <alm-38011__li767116237265>`.
-
-#. .. _alm-38011__li767116237265:
-
-   Check whether the number of real-time connections and connection usage of the current user are sharply increased when they are compared with historical data, and whether have exceeded the specified maximum number of connections.
-
-   -  If yes, go to :ref:`8 <alm-38011__li73329221446>`.
-   -  If no, go to :ref:`9 <alm-38011__li153332221440>`.
-
-   .. note::
-
-      If there is an obvious increase after the comparison and the maximum number of connections has reached the preset value, the connections of the user may be abnormal. You need to confirm with the service party.
-
-**Check whether the number of user connections meets service requirements.**
-
-8.  .. _alm-38011__li73329221446:
-
-    Check whether the number of connections of the user meets service requirements.
-
-    -  If yes, go to :ref:`9 <alm-38011__li153332221440>`.
-    -  If no, contact the service party to rectify the fault.
-
-    .. note::
-
-       If the number of user connections is abnormal, contact the service party to rectify the fault from the following aspects:
-
-       -  Check whether new services are added so that the number of user connections increases sharply.
-       -  Check whether handle leakage occurs on the code at the service side.
-
-9.  .. _alm-38011__li153332221440:
-
-    Consider whether to increase the maximum number of connections of the user.
-
-    -  If yes, go to :ref:`10 <alm-38011__li123335223414>`.
-    -  If no, go to :ref:`12 <alm-38011__li17333142212420>`.
-
-10. .. _alm-38011__li123335223414:
-
-    Increase the maximum number of connections based on the service requirements. Set the number of connections of the user on the Kafka client. For details, see :ref:`5 <alm-38011__li10246106955>`.
-
-11. Wait for several minutes and then check whether the alarm is automatically cleared.
-
-    -  If yes, go to :ref:`12 <alm-38011__li17333142212420>`.
-    -  If no, go to :ref:`2 <alm-38011__li19192924516>`.
-
-12. .. _alm-38011__li17333142212420:
-
-    Determine whether to add the user to the whitelist based on service requirements on the service side.
-
-    -  If yes, go to :ref:`13 <alm-38011__li173338226416>`.
-    -  If no, go to :ref:`15 <alm-38011__li1473912318017>`.
-
-    .. note::
-
-       To add a user to the whitelist, you need to restart the Kafka service. However, this operation will cause service interruption and affect service running. Therefore, you must confirm with the service side before performing this operation.
-
-13. .. _alm-38011__li173338226416:
-
-    On the FusionInsight Manager home page, choose **Cluster** > *Name of the desired cluster* > **Services** > **Kafka** > **Configurations** > **All Configurations** > **Broker(Role)** > **Server** to add the user to the **max.connections.per.user.whitelist** configuration item.
-
-14. Restart the service for the modification to take effect. In addition, you need to manually clear the alarm, and no further action is required.
-
-**Collect the fault information.**
-
-15. .. _alm-38011__li1473912318017:
-
-    On the FusionInsight Manager homepage, choose **O&M** > **Log** > **Download**.
-
-16. Expand the **Service** drop-down list, and select **Kafka** for the target cluster.
-
-17. Click |image1| in the upper right corner, and set **Start Date** and **End Date** for log collection to 10 minutes ahead of and after the alarm generation time, respectively. Then, click **Download**.
-
-18. Contact the O&M personnel and send the collected fault logs.
-
-Alarm Clearing
---------------
-
-After the fault is rectified, the system automatically clears this alarm.

-
-   **export CLICKHOUSE_CONF_DIR=${CLICKHOUSE_CONF_DIR}**
-
-7. Run the following command to run the metadata synchronization tool to synchronize metadata from the existing node to the faulty node:
-
-   **sh** *Cluster installation directory*\ **/FusionInsight_ClickHouse_*/install/FusionInsight-ClickHouse-*/clickhouse/sbin/clickhouse-create-meta.sh** **true**
-
-8. Run the following command to view the log information and check whether the metadata has been synchronized:
-
-   **vim /var/log/Bigdata/clickhouse/clickhouseServer/start.log**
-
-   -  If the synchronization is complete, go to :ref:`9 <alm-45429__li185513552368>`.

-
-   **source** *Cluster installation directory*\ **/FusionInsight_ClickHouse_*/*_*_ClickHouseServer/etc/clickhouse-env.sh**
-
-   **export CLICKHOUSE_CONF_DIR=${CLICKHOUSE_CONF_DIR}**
-
-7. Run the following command to run the metadata synchronization tool to synchronize metadata from the existing node to the faulty node:
-
-   **sh** *Cluster installation directory*\ **/FusionInsight_ClickHouse_*/install/FusionInsight-ClickHouse-*/clickhouse/sbin/clickhouse-create-meta.sh** **true**
-
-8. Run the following command to view the log information and check whether the metadata has been synchronized:
-
-   **vim /var/log/Bigdata/clickhouse/clickhouseServer/start.log**
-
-   If the synchronization is complete, go to :ref:`9 <alm-45430__li185513552368>`.

-ALM-45589 ConfigNode Heap Memory Usage Exceeds the Threshold
-============================================================
-
-Description
------------
-
-The system checks the heap memory usage of the ConfigNode process every 60 seconds. This alarm is generated when the heap memory usage of the ConfigNode process exceeds the threshold (90% of the maximum memory). This alarm is cleared when the heap memory usage of the ConfigNode process is less than the threshold.

-Description
------------
-
-If a large number of write-ahead logs (WALs) are stacked in the PostgreSQL database, the PostgreSQL disk space may be used up. The system checks whether the amount of data queued in the replication slot configured for a CDL job exceeds the threshold every 5 minutes. This alarm is generated when the amount of data queued in the replication slot exceeds the threshold. This alarm is cleared when the number of data queued in the replication slot falls below the threshold.

-Backing Up CDL Data
-===================
-
-Scenario
---------
-
-To ensure CDL service data security routinely or before a major operation on CDL (such as upgrade or migration), you need to back up CDL data. The backup data can be used to recover the system if an exception occurs or the operation has not achieved the expected result, minimizing the adverse impacts on services.
-
-CDL data is stored in DBService and Kafka. You can create DBService and Kafka backup tasks on FusionInsight Manager to back up CDL data. Both automatic and manual backup tasks are supported.
-
-Prerequisites
--------------
-
--  If data needs to be backed up to the remote HDFS, you have prepared a standby cluster for data backup. The authentication mode of the standby cluster is the same as that of the active cluster. For other backup modes, you do not need to prepare the standby cluster.
--  If the active cluster is deployed in security mode and the active and standby clusters are not managed by the same FusionInsight Manager, mutual trust has been configured. For details, see :ref:`Configuring Cross-Manager Mutual Trust Between Clusters <admin_guide_000177>`. If the active cluster is deployed in normal mode, no mutual trust is required.
--  Cross-cluster replication has been configured for the active and standby clusters. For details, see :ref:`Enabling Cross-Cluster Replication <admin_guide_000200>`.
--  Time is consistent between the active and standby clusters and the NTP services on the active and standby clusters use the same time source.
--  The backup type, period, policy, and other specifications have been planned based on the service requirements and you have checked whether *Data storage path*\ **/LocalBackup/** has sufficient space on the active and standby management nodes.
--  If you want to back up data to NAS, you have deployed the NAS server in advance.
--  If you want to back up data to OBS, you have connected the current cluster to OBS and have the permission to access OBS.
-
-Procedure
----------
-
-#. On FusionInsight Manager, choose **O&M** > **Backup and Restoration** > **Backup Management**.
-
-#. Click **Create**.
-
-#. Set **Name** to the name of the backup task.
-
-#. Select the cluster to be operated from **Backup Object**.
-
-#. Set **Mode** to the type of the backup task.
-
-   **Periodic** indicates that the backup task is executed by the system periodically. **Manual** indicates that the backup task is executed manually.

-Backing Up IoTDB Metadata
-=========================
-
-Scenario
---------
-
-To ensure IoTDB metadata security and prevent the IoTDB service from being unavailable due to IoTDB metadata file damages, you need to back up IoTDB metadata. The backup data can be used to recover the system if an exception occurs or the operation has not achieved the expected result, minimizing the adverse impacts on services.
-
-You can create a backup task on FusionInsight Manager to back up IoTDB metadata. Both automatic and manual backup tasks are supported.
-
-Prerequisites
--------------
-
--  The backup type, period, policy, and other specifications have been planned based on the service requirements and you have checked whether *Data storage path*\ **/LocalBackup/** has sufficient space on the active and standby management nodes.
-
--  If you want to back up data to NAS, you have deployed the NAS server in advance.
-
--  Time is consistent between the active and standby clusters and the NTP services on the active and standby clusters use the same time source.
-
--  Backup policies, including the backup task type, period, backup object, backup directory, and Yarn queue required by the backup task are planned based on service requirements.
--  The HDFS in the standby cluster has sufficient space. You are advised to save backup files in a custom directory.
-
-Procedure
----------
-
-#. On FusionInsight Manager, choose **O&M** > **Backup and Restoration** > **Backup Management**.
-
-#. Click **Create**.
-
-#. Set **Name** to the name of the backup task.
-
-#. Select the cluster to be operated from **Backup Object**.
-
-#. Set **Mode** to the type of the backup task.
-
-   **Periodic** indicates that the backup task is executed by the system periodically. **Manual** indicates that the backup task is executed manually.

-Backing Up IoTDB Service Data
-=============================
-
-Scenario
---------
-
-To ensure IoTDB service data security routinely or before a major operation on IoTDB (such as upgrade or migration), you need to back up IoTDB service data. The backup data can be used to recover the system if an exception occurs or the operation has not achieved the expected result, minimizing the adverse impacts on services.
-
-You can create a backup task on FusionInsight Manager to back up IoTDB service data. Both automatic and manual backup tasks are supported.
-
-Prerequisites
--------------
-
--  If data needs to be backed up to the remote HDFS, you have prepared a standby cluster for data backup. The authentication mode of the standby cluster is the same as that of the active cluster. For other backup modes, you do not need to prepare the standby cluster. Currently, IoTDB data can be backed up only to HDFS.
--  For the IoTDB cluster in normal mode, service data cannot be backed up to HDFS in a cluster in security mode.
-
--  If the active cluster is deployed in security mode and the active and standby clusters are not managed by the same FusionInsight Manager, mutual trust has been configured. For details, see :ref:`Configuring Cross-Manager Mutual Trust Between Clusters <admin_guide_000177>`. If the active cluster is deployed in normal mode, no mutual trust is required.
-
--  Time is consistent between the active and standby clusters and the NTP services on the active and standby clusters use the same time source.
--  The HDFS in the standby cluster has sufficient space. You are advised to save backup files in a custom directory.
-
-Procedure
----------
-
-#. On FusionInsight Manager, choose **O&M** > **Backup and Restoration** > **Backup Management**.
-
-#. Click **Create**.
-

-
-#. In **Configuration**, choose **IoTDB** > **IoTDB** under **Service data**.
-
-#. Set **Path Type** of **IoTDB** to a backup directory type.
-
-   The following backup directory types are supported:
-
-   **RemoteHDFS**: indicates that the backup files are stored in the HDFS directory of the standby cluster.
-
-   If you select this option, set the following parameters:
-
-   -  **Destination NameService Name**: indicates the NameService name of the standby cluster, for example, **hacluster**. You can obtain it from the **NameService Management** page of HDFS of the standby cluster.
-
-   -  **IP Mode**: indicates the mode of the target IP address. The system automatically selects the IP address mode based on the cluster network type, for example, **IPv4** or **IPv6**.
-   -  **Destination Active NameNode IP Address**: indicates the service plane IP address of the active NameNode in the standby cluster.
-   -  **Destination Standby NameNode IP Address**: indicates the service plane IP address of the standby NameNode in the standby cluster.
-   -  **Destination NameNode RPC Port**: indicates the value of **dfs.namenode.rpc.port** in the HDFS basic configuration of the standby cluster.
-   -  **Target Path**: indicates the HDFS directory for storing standby cluster backup data. The storage path cannot be an HDFS hidden directory, such as a snapshot or recycle bin directory, or a default system directory, such as **/hbase** or **/user/hbase/backup**.
-   -  **Maximum Number of Backup Copies**: indicates the number of backup file sets that can be retained in the backup directory.
-
-#. Set **Backup Content** to one or multiple service data records to be backed up.
-
-   You can select backup data using either of the following methods:
-
-   -  Adding a backup data file
-
-      Click the name of a database in the navigation tree to show all the tables in the database, and select specified tables.
-
-      MRS 3.2.0 or later:

-      a. Click **Add**.
-      b. Select the table to be backed up under **File Directory**, and click **Add** to add the table to **Backup Content**.
-      c. Click **OK**.
-
-   -  Selecting using regular expressions
-
-      a. Click **Query Regular Expression**.
-      b. Enter the parent directory full path of the directory in the first text box as prompted. The directory must be the same as the existing directory, for example, **/root**.
-      c. Enter a regular expression in the second text box. Standard regular expressions are supported. For example, to get all files or subdirectories in the parent directory, enter **([\\s\\S]*?)**. To get files whose names consist of letters and digits, for example, **file\ 1**, enter **file\\d\***.
-      d. Enter a regular expression in the second text box. Standard regular expressions are supported. For example, to get objects containing **test**, enter **.*test.\***. To get objects starting with **test**, enter **test.\***. To get objects ending with **test**, enter **.*test**.
-      e. Click **Refresh** to view the displayed directories in **Directory Name**.
-      f. Click **Synchronize** to save the result.
-
-      .. note::
-
-         -  When entering regular expressions, click |image1| or |image2| to add or delete an expression.
-         -  If the selected table or directory is incorrect, click **Clear Selected Node** to deselect it.
-         -  The backup directory cannot contain files that have been written for a long time. Otherwise, the backup task will fail. Therefore, you are not advised to perform operations on the top-level directory, such as **/user**, **/tmp**, and **/mr-history**.
-
-#. Click **Verify** to check whether the backup task is configured correctly.
-
-   The possible causes of the verification failure are as follows:
-
-   -  The target NameNode IP address is incorrect.
-   -  The data to be backed up does not exist.
-
-#. Click **OK**.
-
-#. In the **Operation** column of the created task in the backup task list, click **More** and select **Back Up Now** to execute the backup task.
-
-   After the backup task is executed, the system automatically creates a subdirectory for each backup task in the backup directory. The format of the subdirectory name is *Backup task name_Data source_Task creation time*, and the subdirectory is used to save latest data source backup files. All the backup file sets are stored in the related snapshot directories.

-Restoring CDL Data
-==================
-
-Scenario
---------
-
-CDL data needs to be restored in the following scenarios: Data is modified or deleted unexpectedly and needs to be restored. After an administrator performs major operations (such as upgrade and data adjustment) on CDL, an exception occurs or the expected result is not achieved. All modules are faulty and become unavailable. Data is migrated to a new cluster.
-
-CDL metadata is stored in DBService and Kafka. A system administrator can create DBService and Kafka restoration tasks on FusionInsight Manager to restore CDL data. Only manual restoration tasks are supported.
-
-.. important::
-
-   -  Data restoration can be performed only when the system version is consistent with that during data backup.
-   -  To restore the data when services are normal, manually back up the latest management data first and then restore the data. Otherwise, the DBService and Kafka data that is generated after the data backup and before the data restoration will be lost.
-   -  By default, MRS clusters use DBService to store metadata of Hive, Hue, Loader, Spark, CDL, and Oozie. Restoring DBService data will restore the metadata of all these components.
-
-Impact on the System
---------------------
-
--  After the data is restored, the data generated after the data backup and before the data restoration is lost.
--  After the data is restored, the configurations of the components that depend on DBService may expire and these components need to be restarted.
--  After the metadata is restored, the offset information stored on ZooKeeper by Kafka consumers is rolled back, resulting in repeated consumption.
-
-Prerequisites
--------------
-
--  If you need to restore data from a remote HDFS, prepare a standby cluster. If the active cluster is deployed in security mode and the active and standby clusters are not managed by the same FusionInsight Manager, mutual trust must be configured. For details, see :ref:`Configuring Cross-Manager Mutual Trust Between Clusters <admin_guide_000177>`. If the active cluster is deployed in normal mode, no mutual trust is required.
--  Cross-cluster replication has been configured for the active and standby clusters. For details, see :ref:`Enabling Cross-Cluster Replication <admin_guide_000200>`.
--  Time is consistent between the active and standby clusters and the NTP services on the active and standby clusters use the same time source.
-
--  The status of the active and standby DBService instances is normal. If the status is abnormal, data restoration cannot be performed.
-
--  The Kafka service is disabled first, and then enabled upon data restoration.
-
-Procedure
----------
-
-#. On FusionInsight Manager, choose **O&M** > **Backup and Restoration** > **Backup Management**.
-
-#. In the row where the specified backup task is located, choose **More** > **View History** in the **Operation** column to display the historical execution records of the backup task.

-Restoring IoTDB Service Data
-============================
-
-Scenario
---------
-
-IoTDB service data needs to be restored in the following scenarios: Data is modified or deleted unexpectedly and needs to be restored. After an administrator performs major operations (such as upgrade and data adjustment) on IoTDB, an exception occurs or the expected result is not achieved. All modules are faulty and become unavailable. Data is migrated to a new cluster.
-
-System administrators can create an IoTDB restoration task on FusionInsight Manager. Only manual restoration tasks are supported.
-
-.. important::
-
-   -  Data restoration can be performed only when the system version is consistent with that during data backup.
-   -  To restore the data when services are normal, manually back up the latest management data first and then restore the data. Otherwise, the IoTDB data that is generated after the data backup and before the data restoration will be lost.
-
-Impact on the System
---------------------
-
--  During data restoration, user authentication stops and users cannot create new connections.
--  After the data is restored, the data generated after the data backup and before the data restoration is lost.
--  After the data is restored, the IoTDB upper-layer applications need to be started.
-
-Prerequisites
--------------
-
--  If you need to restore data from a remote HDFS, prepare a standby cluster. If the active cluster is deployed in security mode and the active and standby clusters are not managed by the same FusionInsight Manager, mutual trust must be configured. For details, see :ref:`Configuring Cross-Manager Mutual Trust Between Clusters <admin_guide_000177>`. If the active cluster is deployed in normal mode, no mutual trust is required.
-
--  Time is consistent between the active and standby clusters and the NTP services on the active and standby clusters use the same time source.
--  The IoTDB backup file save path is correct.
--  The IoTDB upper-layer applications are stopped.
-
-Procedure
----------
-
-#. On FusionInsight Manager, choose **O&M** > **Backup and Restoration** > **Backup Management**.
-
-#. In the row where the specified backup task is located, choose **More** > **View History** in the **Operation** column to display the historical execution records of the backup task.
-
-   In the window that is displayed, select a success record and click **View** in the **Backup Path** column to view its backup path information and find the following information:
-
-   -  **Backup Object**: indicates the backup data source.
-
-   -  **Backup Path**: indicates the full path where backup files are stored.
-
-      Select the correct path, and manually copy the full path of backup files in **Backup Path**.
-
-#. On FusionInsight Manager, choose **O&M** > **Backup and Restoration** > **Restoration Management**.
-
-#. Click **Create**.
-
-#. Set **Task Name** to the name of the restoration task.
-
-#. Select the cluster to be operated from **Recovery Object**.
-
-#. In **Restoration Configuration**, choose **IoTDB** > **IoTDB** under **Service Data**.
-
-#. .. _admin_guide_000361__li4457996415256:
-
-   Set **Path Type** of **IoTDB** to a backup directory type.
-
-   The following backup directory types are supported:
-
-   **RemoteHDFS**: indicates that the backup files are stored in the HDFS directory of the standby cluster.
-
-   If you select this option, configure the following parameters:
-
-   -  **Source NameService Name**: indicates the NameService name of the backup data cluster, for example, **hacluster**. You can obtain it from the **NameService Management** page of HDFS of the standby cluster.
-   -  **IP Mode**: indicates the mode of the target IP address. The system automatically selects the IP address mode based on the cluster network type, for example, **IPv4** or **IPv6**.
-   -  **Source Active NameNode IP Address**: indicates the service plane IP address of the active NameNode in the standby cluster.
-   -  **Source Standby NameNode IP Address**: indicates the service plane IP address of the standby NameNode in the standby cluster.
-   -  **Source NameNode RPC Port**: indicates the value of **dfs.namenode.rpc.port** in the HDFS basic configuration of the standby cluster.
-   -  **Source Path**: indicates the full path of HDFS directory for storing backup data of the standby cluster, for example, *Backup path/Backup task name_Data source_Task creation time*.
-   -  **Recovery Point List**: Click **Refresh** and select an IoTDB directory that has been backed up in the standby cluster.
-
-#. In the **Backup Data** column of the **Data Configuration** page, select one or more pieces of backup data that needs to be restored based on service requirements. In the **Target Path** column, specify the target location after backup data restoration.
-
-   You are advised to set **Target Path** to a new path that is different from the backup path.
-
-#. Set **Force recovery** to **true**, which indicates that all backup data is forcibly restored when a data table with the same name already exists. If the data table contains new data added after backup, the new data will be lost after the data restoration. If you set the parameter to **false**, the restoration task is not executed if a data table with the same name exists.
-
-#. Click **Verify** to check whether the restoration task is configured correctly.
-
-   -  If the queue name is incorrect, the verification fails.
-   -  If the specified directory to be restored does not exist, the verification fails.
-
-#. Click **OK**.
-
-#. In the restoration task list, locate the row where the created task is located, and click **Start** in the **Operation** column.
-
-   -  After the restoration is successful, the progress bar is in green.
-   -  After the restoration is successful, the restoration task cannot be executed again.
-   -  If the restoration task fails during the first execution, rectify the fault and click **Retry** to execute the task again.

-CDL Basic Principles
-====================
-
-Overview
---------
-
-Change Data Loader (CDL) is a real-time data integration service based on Kafka Connect. The CDL service captures data change events from various OLTP databases and push them to Kafka. Then, Sink Connector pushes the events to the big data ecosystem.
-
-Currently, CDL supports MySQL, PostgreSQL, Oracle, Hudi, Kafka, and ThirdParty-Kafka data sources. Data can be written to Kafka, Hudi, DWS, and ClickHouse.
-
-CDL structure
--------------
-
-The CDL service contains two important roles: CDLConnector and CDLService. CDLConnector, including Source Connector and Sink Connector, is the instance for executing data capture jobs. CDLService is the instance for managing and creating jobs.
-
-|image1|
-
-The CDLService instances of the CDL service work in multi-active mode. Any CDLService instance can perform service operations. The CDLConnector instances work in distributed mode and provide HA and rebalance capabilities. When tasks are created, the number of tasks specified is balanced among CDLConnector instances in a cluster to ensure that the number of tasks running on each instance is similar. If a CDLConnector instance is abnormal or a node breaks down, the number of tasks are rebalanced on other nodes.

-Relationship Between CDL and Other Components
-=============================================
-
-The CDL component is based on the Kafka Connect framework. Captured data is forwarded using Kafka topics. Therefore, the CDL component depends on the Kafka component. In addition, the CDL component stores task metadata and monitoring information that are also stored in a database. Therefore, the CDL component also depends on the DBService component.

-IoTDB Basic Principles
-======================
-
-Database for Internet of Things (IoTDB) is a software system that collects, stores, manages, and analyzes IoT time series data. Apache IoTDB uses a lightweight architecture and features high performance and rich functions.
-
-IoTDB sorts time series and stores indexes and chunks, greatly improving the query performance of time series data. IoTDB uses the Raft protocol to ensure data consistency. In time series scenarios, IoTDB pre-computes and stores data to improve analysis performance. Based on the characteristics of time series data, IoTDB provides powerful data encoding and compression capabilities. In addition, its replica mechanism ensures data security. IoTDB is deeply integrated with Apache Hadoop and Flink to meet the requirements of massive data storage, high-speed data reading, and complex data analysis in the industrial IoT field.
-
-IoTDB Architecture
-------------------
-
-The IoTDB suite consists of multiple components to provide a series of functions such as data collection, data writing, data storage, data query, data visualization, and data analysis.
-
-:ref:`Figure 1 <mrs_08_0094__fig121405277474>` shows the overall application architecture after all components of the IoTDB suite are used. IoTDB refers to the time series database component in the suite.

-
-   **Figure 1** IoTDB architecture
-
--  Users can use Java Database Connectivity (JDBC) or Session to import the time series data and system status data (such as server load, CPU usage and memory usage) collected from device sensors, as well as time series data in message queues, applications, or other databases, to the local or remote IoTDB. Users can also directly write the preceding data into a local TsFile file or a TsFile file in the HDFS.
--  Users can write TsFile files to the HDFS to implement data processing tasks such as exception detection and machine learning on the Hadoop or Flink data processing platform.
--  The TsFile-Hadoop or TsFile-Flink connector can be used to allow Hadoop or Flink to process the TsFile files written to the HDFS or local host.
--  The analysis result can be written back to a TsFile in the same way.
--  IoTDB and TsFile also provide client tools to meet users' requirements for viewing and writing data in SQL, script, and graphical formats.
-
-The IoTDB service includes two roles: IoTDBServer (DataNode) and ConfigNode. The role name DataNode of the community edition has the same name as the HDFS role. DataNode is renamed IoTDBServer.
-
--  ConfigNode: management role, which is responsible for DataNode data sharding and load balancing.
--  IoTDBServer (DataNode): storage role, which is responsible for storing, querying, and writing data.

-
-IoTDB Principles
-----------------
-
-Based on the attribute hierarchy, attribute coverage, and subordinate relationships between data, the IoTDB data model can be represented as the attribute hierarchy, as shown in :ref:`Figure 3 <mrs_08_0094__fig1285721116>`. The hierarchy is as follows: power group layer - power plant layer - device layer - sensor layer. **ROOT** is a root node, and each node at the sensor layer is a leaf node. According to the IoTDB syntax, the path from **ROOT** to a leaf node is separated by a dot (.). The complete path is used to name a time series in the IoTDB. For example, the time series name corresponding to the path on the left in the following figure is **ROOT.ln.wf01.wt01.status**.

-IoTDB Enhanced Open Source Features
-===================================
-
-Visualization
--------------
-
--  Visualized O&M covers installation, uninstallation, one-click start and stop, configurations, clients, monitoring, alarms, health checks, and logs.
--  Visualized permission management does not require background command line operations and supports read and write permission control at the database and table levels.
--  Visualized log level configuration dynamically takes effect, supports visualized download and retrieval, and supports log audit.
-
-Security Hardening
-------------------
-
-User authentication supports Kerberos authentication and SSL encryption, which are compatible with the community authentication mode.
-
-Ecosystem Interconnection
--------------------------
-
-On the basis of native capabilities, the cluster interconnection with MQTT and CoAP is enhanced.

-Relationship Between IoTDB and Other Components
-===============================================
-
-The IoTDB stores data locally, so it does not depend on any other component for storage. However, in a security cluster environment, IoTDB depends on the KrbServer component for Kerberos authentication.

 For clusters in security mode with Kerberos authentication enabled, security authentication is required during application development.
 
-Kerberos, is now used to a concept in authentication. The Kerberos protocol adopts a client-server model and cryptographic algorithms such as AES (Advanced Encryption Standard). It provides mutual authentication, that is, both the client and the server can verify each other's identity. Kerberos is used to prevent interception and replay attacks and protect data integrity. It is a system that manages keys by using a symmetric key mechanism.
