Rohith commented on YARN-2579:
------------------------------

bq. We should avoid these dispatcher events trying to close the dispatchers - that was why
I suggested a separate thread (my point 2.2 in the proposal
I missed in YARN-2579-20141105.patch.  Later I updated patch considering separate thread i.e
YARN-2579-20141105.1.patch. 
{code}
-      type = RMFatalEventType.STATE_STORE_FENCED;
+      Thread standByTransitionThread =
+          new Thread(new StandByTransitionThread());
+      standByTransitionThread.setName("StandByTransitionThread Handler");
+      standByTransitionThread.start();
{code}
