Weiwei Yang updated YARN-4621:
------------------------------
Description:
RM tried allocated more than 10 containers on a NM (on which time is out of
sync), they all failed with token expired error, and job eventually failed. We
can add a new state to NodeState, e.g UNSYNC, if a node is not sync'd with RM,
RM then can skip allocating containers on this node.
