Andrew Purtell commented on HBASE-5964:
---------------------------------------

We should commit this, doing anything else with recent branch-2 requires it.

> Not sure precisely when it started. First I thought it might be due to HBASE-5955 but
I cherry picked that change over from trunk. Then I got HBASE-5963 out of the way.
