shengjk1 commented on FLINK-11336:
----------------------------------
1.No matter what form stop flink, such as cancel,failed with no further
retries,kill, metadata not be deleted.
2.when cancel,failed with no further retries,kill,manually deleting metadata
has no effect on newly launched programs even if there has a savepoint
this is my observed behavior
> Flink HA didn't remove ZK metadata
