Key Default Type Description
high-availability.zookeeper.client.acl
"open" String Defines the ACL (open|creator) to be configured on ZK node. The configuration value can be set to “creator” if the ZooKeeper server configuration has the “authProvider” property mapped to use SASLAuthenticationProvider and the cluster is configured to run in secure mode (Kerberos).
high-availability.zookeeper.client.connection-timeout
15 s Duration Defines the connection timeout for ZooKeeper.
high-availability.zookeeper.client.ensemble-tracker
true Boolean Defines whether Curator should enable ensemble tracker. This can be useful in certain scenarios in which CuratorFramework is accessing to ZK clusters via load balancer or Virtual IPs. Default Curator EnsembleTracking logic watches CuratorEventType.GET_CONFIG events and changes ZooKeeper connection string. It is not desired behaviour when ZooKeeper is running under the Virtual IPs. Under certain configurations EnsembleTracking can lead to setting of ZooKeeper connection string with unresolvable hostnames.
high-availability.zookeeper.client.max-retry-attempts
3 Integer Defines the number of connection retries before the client gives up.
high-availability.zookeeper.client.retry-wait
5 s Duration Defines the pause between consecutive retries.
high-availability.zookeeper.client.session-timeout
1 min Duration Defines the session timeout for the ZooKeeper session.
high-availability.zookeeper.client.tolerate-suspended-connections
false Boolean Defines whether a suspended ZooKeeper connection will be treated as an error that causes the leader information to be invalidated or not. In case you set this option to true, Flink will wait until a ZooKeeper connection is marked as lost before it revokes the leadership of components. This has the effect that Flink is more resilient against temporary connection instabilities at the cost of running more likely into timing issues with ZooKeeper.
high-availability.zookeeper.path.jobgraphs
"/jobgraphs" String ZooKeeper root path (ZNode) for job graphs
