Weiwei Yang commented on YARN-4621:
-----------------------------------
If a NM is desync (system time out of sync with RM .. more than 5 minutes gap
?), then list it as unusable ?
> Job failed if time on one NM is out of sync even other nodes are sync'd
> -----------------------------------------------------------------------

> 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 DESYNC, if a node is not sync'd with
> RM, RM then can skip allocating containers on this node.
