-----------------------------------

             Summary: The DispatcherThreadFactory should register uncaught exception handlers
                 Key: FLINK-8884
                 URL: https://issues.apache.org/jira/browse/FLINK-8884
             Project: Flink
          Issue Type: Bug
          Components: TaskManager
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.5.0, 1.6.0


The {{DispatcherThreadFactory}} is responsible for spawning the thread pool threads for TaskManager's async dispatcher and for the CheckpointCoordinators timed trigger.

In case of uncaught exceptions in these threads, the system is not healthy and more, hence they should register the {{FatalExitUcaughtExceptionsHandler}}.
