             Summary: Checkpoint cleanup can kill JobMaster
                 Key: FLINK-20992
                 URL: https://issues.apache.org/jira/browse/FLINK-20992
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Checkpointing
    Affects Versions: 1.12.0
            Reporter: Till Rohrmann
             Fix For: 1.13.0, 1.12.2


A user reported that cancelling a job can lead to an uncaught exception which kills the {{JobMaster}}. The problem seems to be that the {{CheckpointsCleaner}} might trigger {{CheckpointCoordinator}} actions after the job has reached a terminal state and, thus, is shut down. Apparently, we do not properly manage the lifecycles of {{CheckpointCoordinator}} and checkpoint post clean up actions.

The uncaught exception is 

{code}
