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

             Summary: When RM transit from Active to Standby, the same eventDispatcher should
not be registered more than once
                 Key: YARN-1574
                 URL: https://issues.apache.org/jira/browse/YARN-1574
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Xuan Gong
            Assignee: Xuan Gong
            Priority: Blocker


Currently, we move rmDispatcher out of ActiveService. But we still register the Event dispatcher,
such as schedulerDispatcher, RMAppEventDispatcher when we initiate the ActiveService.

Almost every time when we transit RM from Active to Standby,  we need to initiate the ActiveService.
That means we will register the same event Dispatcher which will cause the same event will
be handled several times.
