---------------------------
Resolution: Not A Bug
> resource leak when job failed with unknown status In Application Mode
> ---------------------------------------------------------------------
>
> Key: FLINK-28499
> URL: https://issues.apache.org/jira/browse/FLINK-28499
> Project: Flink
> Issue Type: Bug
> Components: Deployment / Kubernetes
> Affects Versions: 1.13.1
> Reporter: lihe ma
> Priority: Major
> Attachments: cluster-pod-error.png
>
>
> I found a job restarted for thousands of times, and jobmanager tried to
> create a new taskmanager pod every time. The jobmanager restarted because
> submitted with duplicate job id[1] (we preset the jobId rather than
> generate), but I hadn't save the logs unfortunately.
> this job requires one taskmanager pod in normal circumstances, but thousands
> of pods were leaked finally. you can find the screenshot in the attachment.
>
> In application mode, cluster resources will be released when job finished in
> succeeded, failed or canceled status[2][3] . When some exception happen, the
> job may be terminated in unknown status[4] .
> In this case, the job exited with unknown status , without releasing
> taskmanager pods. So is it reasonable to not release taskmanager when job
> exited in unknown status ?
