Wangda Tan commented on YARN-2139:
----------------------------------
Thanks [~bikassaha] and [~kasha],
+1 for work on a branch, there might be some great amount of changes across all
the major modules, frequently rebasing might be a issue if this is based on
trunk.
And also totally agree about having an abstract policy to wrap disk affinity /
iops / bandwidth, etc.
