Multiple branches for MOB feature breaking git for case insensitive filesystems

The feature branch for MOB work (HBASE-11339) at some recent point split into two divergent branches that differ by case in their name (hbase-11339 v HBASE-11339).

Per the mailing list, this is breaking git on filesystems that are case insensitive, namely Mac OS X.

This isn't just an annoyance. Clearly active dev is happening on
"hbase-11339", last commit:

HBASE-12392 Incorrect implementation of

CompactionRequest.isRetainDeleteMarkers(Jingcheng Du)

and this commit, HBASE-12392, is missing on "hbase-11339", so whatever it
is supposed to fix isn't fixed there.

We need for someone working on MOB to commit HBASE-12392 into "hbase-11339"
and then drop the "HBASE-11339" branch. Thanks!
