Jason Lowe updated HADOOP-15027:
--------------------------------
Fix Version/s: (was: 3.0.1)
(was: 2.9.1)
(was: 2.10.0)
I reverted this from branch-3.0, branch-2 and branch-2.9 since it broke the
builds there:

If this needs to go into those releases, please revisit the patches for those
branches. Looks like this patch depends upon HADOOP-15039 which only went into
3.1.0.
