If the HA related ConfigMaps still exists, then I am afraid the data
located on the distributed storage should also exist.
So I suggest to delete the HA related storage as well.
Delete all the HA related data manually should help in your current
situation. After then you could recover from the new savepoint.
However, I do not think this is a normal behavior. Since when the
application reached the terminal state(e.g. FINISHED, FAILED, CANCELLED),
all HA related data should be cleaned up automatically.
Could you help to provide the JobManager logs when you are trying to cancel
the job? I believe using `kubectl logs -f {pod_name}` could dump
the logs in real time.
Best,
Yang
