Jeff Zhang commented on TEZ-1564:
---------------------------------
Check it again, vertex (Map 5) is scheduled 2 times. And both are in
onSourceTaskCompleted, and in the same thread (AsyncDispatcher event handler),
not sure why it is scheduled 2 times. [~rajesh.balamohan] Have you see this
error again ?
