[jira] [Created] (FLINK-3443) JobManager cancel and clear everything fails jobs instead of cancelling

Ufuk Celebi created FLINK-3443:
----------------------------------

             Summary: JobManager cancel and clear everything fails jobs instead of cancelling
                 Key: FLINK-3443
                 URL: https://issues.apache.org/jira/browse/FLINK-3443
             Project: Flink
          Issue Type: Bug
          Components: Distributed Runtime
            Reporter: Ufuk Celebi
            Assignee: Ufuk Celebi


When the job manager is shut down, it calls {{cancelAndClearEverything}}. This method does not {{cancel}} the {{ExecutionGraph}} instances, but {{fail}}s them, which can lead to {{ExecutionGraph}} restart.

I've noticed this in tests, where old graph got into a loop of restarts.

What I don't understand is why the futures etc. are not cancelled when the executor service is shut down.
