Subject [jira] [Created] (FLINK-3800) ExecutionGraphs can become orphans

Till Rohrmann created FLINK-3800:
------------------------------------

             Summary: ExecutionGraphs can become orphans
                 Key: FLINK-3800
                 URL: https://issues.apache.org/jira/browse/FLINK-3800
             Project: Flink
          Issue Type: Bug
          Components: JobManager
    Affects Versions: 1.0.0, 1.1.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann


The {{JobManager.cancelAndClearEverything}} method fails all currently executed jobs on the
{{JobManager}} and then clears the list of {{currentJobs}} kept in the JobManager. This can
become problematic if the user has set a restart strategy for a job, because the {{RestartStrategy}}
will try to restart the job. This can lead to unwanted re-deployments of the job which consumes
resources and thus will trouble the execution of other jobs. If the restart strategy never
stops, then this prevents that the {{ExecutionGraph}} from ever being properly terminated.
