Nico Kruber commented on FLINK-11789:
-------------------------------------
One more thing to consider: I was using Azure Blob Storage for the checkpoints
and savepoints directories and a job with no checkpoints. Now, I took some
savepoints and still have the aforementioned directories lying around (while
the job is running and afterwards as elaborated above). Since a savepoint
essentially/almost does the same thing as a checkpoint, I do get the part of
these directories being there, but without active checkpoints, they are
strictly not even necessary in the first place.
However, I just wanted to point out that this also affects jobs with savepoints
only.

> Components: Runtime / Checkpointing
> Affects Versions: 1.9.0
> Reporter: Till Rohrmann
> Priority: Major
>
> Flink currently does not clean up all checkpoint directories when a job
> reaches a globally terminal state. Having configured the checkpoint directory
> {{checkpoints}}, I observe that after cancelling the job {{JOB_ID}} there are
> still
> {code}
> checkpoints/JOB_ID/shared
> checkpoints/JOB_ID/taskowned
> {code}
> I think it would be good if would delete {{checkpoints/JOB_ID}}
