In case of entering the wrong job manager address when submitting a job via flink run, the JobClientActor waits per default 60 s until a JobClientActorConnectionException, indicating that the JobManager is no longer reachable, is thrown. In order to fail fast in case of wrong connection information, we could change it such that it uses initially a much lower timeout and only increases the timeout if it had at least once successfully connected to a JobManager before.
