Xiao Chen commented on HADOOP-13866:
------------------------------------
Thanks all for the comment.
So to summarize: let's revert HDFS-8377 from trunk, to ease this jira. Plan to
revert from branch-2 to make it closer to trunk.
branch-2.8 will be left as-is.
[~tedyu], this jira is only targeting for 3.0 right? So we don't need to worry
about bringing this to branch-2 (specifically branch-2.8)
