Wangda Tan updated YARN-1502:
-----------------------------
Attachment: yarn-1502.1.patch
Attached the first patch of scheduler changes for preview, just to want to know
if I have any big issue of this approach.
Currently this still in development, container increasing is supported and have
unit tests, but container decreasing not tested yet.
Hope you can share some light to me! :)
