-----------------------------------

             Summary: Kubernetes Native in HA Application Mode does not retry resource cleanup
                 Key: FLINK-26772
                 URL: https://issues.apache.org/jira/browse/FLINK-26772
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.15.0
            Reporter: Mika Naylor


I set up a scenario in which a k8s native cluster running in Application Mode used an s3 bucket for it's high availability storage directory, with the hadoop plugin. The credentials the cluster used gives it permission to write to the bucket, but not delete, so cleaning up the blob/jobgraph will fail.

I expected that when trying to clean up the HA resources, it would attempt to retry the cleanup. I even configured this explicitly:

{{cleanup-strategy: fixed-delay
cleanup-strategy.fixed-delay.attempts: 100
cleanup-strategy.fixed-delay.delay: 10 s}}

However, the behaviour I observed is that the blob and jobgraph cleanup is only attempted once. After this failure, I observe in the logs that:

{{2022-03-21 09:34:40,634 INFO  org.apache.flink.client.deployment.application.ApplicationDispatcherBootstrap [] - Application completed SUCCESSFULLY
2022-03-21 09:34:40,635 INFO  org.apache.flink.runtime.entrypoint.ClusterEntrypoint        [] - Shutting KubernetesApplicationClusterEntrypoint down with application status SUCCEEDED. Diagnostics null.}}

After which, the cluster recieves a SIGTERM an exits.
