Oleksandr Nitavskyi updated FLINK-31780:
----------------------------------------
Description:
In Apache Curator an option to skip ensemble tracking was added since version
5.0.0 ([CURATOR-568|https://issues.apache.org/jira/browse/CURATOR-568])
This can be useful in certain scenarios in which CuratorFramework is accessing
to ZK clusters via load balancer or Virtual IPs.
Thus in case Zookeeper of Flink user is running behind LB or Virtual IP
ensemble tracking could be disabled too.
Moreover enabled ensemble tracking could lead to NPE and thus Flink cluster
failure, even if only single node is not available, see fix in Apache Curator:
https://github.com/apache/curator/pull/433.
*Acceptance Criteria:* Users of Apache Flink has a Zookeeper config option to
disable ensemble tracking for ZooKeeper.
