Stephan Ewen commented on FLINK-11336:
--------------------------------------
Flink should remove the metadata when the job terminates, which means
- finished (for batch and bounded streams)
- failed with no further retries
- cancelled
It does not remove the metadata if you just kill the YARN application or stop
all containers. In that case Flink does not know that this was not a failure,
but an intended shutdown.
Can you confirm that this was a proper termination (as described above).
If yes, which way did you start the Flink job?
