ASF GitHub Bot commented on FLINK-3347: --------------------------------------- GitHub user tillrohrmann opened a pull request: https://github.com/apache/flink/pull/2696 [FLINK-3347] [akka] Add QuarantineMonitor which shuts a quarantined actor system and JVM down The QuarantineMonitor subscribes to the actor system's event bus and listens to AssociationErrorEvents. These are the events which are generated when the actor system has quarantined another actor system or if it has been quarantined by another actor system. In case of the quarantined state, the actor system will be shutdown killing all actors and then the JVM is terminated.

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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
