I totally agree we have too many branches to maintain.

I think we should EOL 1.1. 1.2 has been out and stable for a long time,
doesn't have any outstanding major problems preventing upgrade that I'm
aware of, though obviously Sean would know better.

Speaking of 1.3, there's one issue that I feel needs to be addressed before
we move stable pointer to 1.3 and start EOL-ing 1.2

HBASE-18397, TL;DR - major optimization changes in scanners locking schema
in 1.3 broke store file accounting, which could cause failed long scans,
failed splits and failed snapshots. Many people spent lots and lots of time
fixing various aspects of that, but there are still issues not yet fixed.
Any help in that area would be amazing. This specific issue probably
deserves separate discussion.
