> There are cases where Akka quarantines remote actor systems. In that case, no further communication is possible with that actor system unless one of the two actor systems is restarted.
> The result is that a TaskManager is up and available, but cannot register at the JobManager (Akka refuses connection because of the quarantined state), making the TaskManager a useless process.
> I suggest to let the TaskManager restart itself once it notices that either it quarantined the JobManager, or the JobManager quarantined it.
> It is possible to recognize that by listening to certain events in the actor system event stream: http://stackoverflow.com/questions/32471088/akka-cluster-detecting-quarantined-state
