Xuan Gong updated YARN-365:
---------------------------

    Attachment: YARN-365.4.patch

1.In a single scheduler pass, it will handle all update info.
2.For every events other that node_update event, it will do a node_update first in order to
sync up with the status.
3.Define an atomicInteger to track how many node_update events in CS queue.
4.The RMNode will send out the node_update events either a. RMNode status changes, or b. no
node_update events in CS queue.
