Xiao Chen commented on HADOOP-15012:
------------------------------------
Thanks for the review [[email protected]].
This is the same patch as trunk. Specifically it's the cherry-pick of the trunk
commit bf6a660232b01642b07697a289c773ea5b97217c, with the minimal resolution of
conflicts in the following files:

Will commit to branch-2, and cherry-pick to branch-3.0 once HADOOP-15056 is
fixed in trunk.
