If the disk partition where the cluster installation directory resides is used up, some temporary files will be generated in the program installation directory when running the sed command fails. Users do not have the read, write, and execute permissions of these temporary files. The system reports an alarm indicating that permissions of temporary files are abnormal if these files are within the monitoring range of the alarm. Perform the preceding alarm handling processes to clear the alarm. Alternatively, you can directly delete the temporary files after confirming that files with abnormal permissions are temporary. The temporary file generated after a sed command execution failure is similar to the following.

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.

- 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. +
- 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.

Possible Causes
- The specified timeout duration is shorter than the required execution time.
- The queue resources for task running are insufficient.
- Task data skew occurs. As a result, some tasks process a large amount of data and take a long time to execute.
Procedure
Check whether the timeout interval is correctly set.
-
- On FusionInsight Manager, choose O&M. In the navigation pane on the left, choose Alarm > Alarms. The Alarms page is displayed.
- Select the alarm whose ID is 18020. In the alarm details, view Location to obtain the timeout task name and timeout duration.
- Based on the task name and timeout interval, choose Cluster > Name of the desired cluster > Services > Yarn > ResourceManager (Active) to log in to the native Yarn page. Then find the task on the native page, check its StartTime and calculate the task execution time based on the current system time. Check whether the task execution time exceeds the timeout duration. -
- Evaluate the expected task execution time based on the service and compare it with the task timeout interval.

- Choose Job > Map tasks or Job > Reduce tasks on the left and check whether the execution time of each Map or Reduce task differs greatly. If yes, task data skew occurs. In this case, you need to balance the task data.

ALM-19011 RegionServer Region Number Exceeds the Threshold
Description
The system checks the number of regions on each RegionServer in each HBase service instance every 30 seconds. The region number is displayed on the HBase service monitoring page and RegionServer role monitoring page. This alarm is generated when the number of regions on a RegionServer exceeds the threshold (default value: 2000) for 20 consecutive times. The threshold can be changed by choosing O&M > Alarm > Thresholds > Name of the desired cluster > HBase. This alarm is cleared when the number of regions is less than or equal to the threshold.

ALM-19021 Handler Usage of RegionServer Exceeds the Threshold
+++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.

- There are many replicas configured for the topic.
- The parameter for batch writing producer's messages is inappropriately configured. The service traffic of this topic is too heavy, and the current partition configuration is inappropriate.
Procedure
