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

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.
