Jian He commented on YARN-1644:
-------------------------------
After thinking more, we may not need a version Id. Below is my suggestion:
1) still keep the separate increasedContainers in the protocol
2) If increased-container > RMContainer, RM ignores this.
3) For the race condition on RM recovery, we may fix this by synchronizing
ContainerMangagerImpl#increaseContainer and NM register call.
> RM-NM protocol changes and NodeStatusUpdater implementation to support
> container resizing
