Common ZooKeeper Parameters

Navigation path for setting parameters:

Go to the All Configurations page of ZooKeeper by referring to Modifying Cluster Service Configuration Parameters <mrs_01_2125>. Enter a parameter name in the search box.

Table 1 Parameters
Parameter Description Default Value
skipACL Specifies whether to skip the permission check of the ZooKeeper node. no
maxClientCnxns Specifies the maximum number of connections of ZooKeeper. It is recommended this parameter is set to a larger value in scenarios with a large number of connections. 2000
LOG_LEVEL Specifies the log level. This parameter can be set to DEBUG during commissioning. INFO
acl.compare.shortName Specifies whether to perform ACL authentication only by principal username when the Znode ACL authentication type is SASL. true
synclimit Specifies the interval of synchronization between the follower and leader (unit: tick). If the leader does not respond within the specified time range, the connection cannot be established. 15
tickTime Specifies the duration of a tick (in milliseconds). It is the basic time unit used by ZooKeeper, which defines heartbeat and timeout durations. 4000

Note

The ZooKeeper internal time is determined by ticktime and synclimit. To increase the ZooKeeper internal timeout interval, increase the timeout interval for the client to connect to ZooKeeper.
