For simple jobs, Flink supports queued scheduling. Thus, it might be the
case that one job stays queued up for quite some time until its execution gets
started.
> Make the JobClientActor check periodically if the submitted Job is still
> running and if the JobManager is still alive

>
> In case that the {{JobManager}} dies without notifying possibly connected
> {{JobClientActors}} or if the job execution finishes without sending the
> {{SerializedJobExecutionResult}} back to the {{JobClientActor}}, it might
> happen that a {{JobClient.submitJobAndWait}} never returns.
> I propose to let the {{JobClientActor}} periodically check whether the
> {{JobManager}} is still alive and whether the submitted job is still running.
> If not, then the {{JobClientActor}} should return an exception to complete
> the waiting future.
