-------------------------------------
Jurriaan,
Would you mind posting another patch of this rebased to the latest commit of
master? I can't apply it cleanly since it collides with your changes in
HBASE-12736. I'll take one final look around once hadoop-qa runs on that, but
this looks fantastic. Well done.

> 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.
