MENG DING commented on YARN-1644:
---------------------------------
I think the race condition is still there. Even though the resource is updated
synchronously, NM re-registration can still happen between the time the
increase action is accepted, and the time the resource is updated. We still
need a mechanism for RM to know that there is pending increase going on in NM,
don't we?
