Jeff Zhang commented on TEZ-1816:
---------------------------------
[~sseth] Is it necessary to add dispatcher.await() here ? Is it for any
potential events sent after this handle method ?
DAG.handle is a sync call, will trigger the state machine transition at once.
> It is possible to receive START event when DAG is failed
