Wangda Tan updated YARN-2496:
-----------------------------
    Attachment: YARN-2496.patch

Attached patch, this patch is based on trunk, but it cannot be compiled itself.
It will be hard to separate YARN-2500 with YARN-2496 and make each of them can be compiled. I split them just for easier reviewing.

This patch is based on YARN-2493 -> YARN-2494 > YARN-2500, you need apply these patches.
