Subject [jira] [Commented] (FLINK-3347) TaskManager (or its ActorSystem) need to restart in case they notice quarantine
Date Thu, 27 Oct 2016 11:56:58 GMT

ASF GitHub Bot commented on FLINK-3347:

Github user StephanEwen commented on the issue:

    Looks good to me.
    I would suggest to rename `taskmanager.quarantine-monitor.enable` to make it more accessible
to users (few will understand what quarantine means). We could call it `taskmanager.exit-on-fatal-akka-error`
or so.
    Otherwise +1 to merge this

> 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
> 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
