> 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.
