stack commented on HBASE-12740:
-------------------------------
Pardon me. I applied v3 with [~dimaspivak] items addressed. Was then trying to
cherry-pick to branch-1 and beyond but was taking a little while (TestHBaseFsck
runs are a bit of beast). I reverted my master work since [~jurmous] showed up
w/ new version. Will go forward with v4.

> TestHBaseFsck performs poor on my machine. It crashes because the threads
> reach the 2000 thread limit on my machine. Looking at the code a lot of
> optimization is possible and some API calls are used wrong. A lot of Admin
> instances are created and never closed, lots of Tables are not closed,
> ThreadPoolExecutors are not shut down and an unlimited thread pool which does
> not recycle threads.
