Hello, I noticed there's a change [1] coming up in Flink 1.14.0 in the ZooKeeper tree structure ZooKeeper HA services maintains.
I didn't spot any migration logic from the old (< 1.14.0) structure to the new. Did I miss something? If you have a Flink cluster running with 1.13.X and let's say add a JobManage with 1.14.0 and terminate the original so that the new one becomes the leader, how's the new one going to understand the data in ZooKeeper? There are naturally more cases where the same compatibility issue should be handled, this example should illustrate the issue. Regards, Juha [1] https://issues.apache.org/jira/browse/FLINK-22636
