----------------------------------
Attachment: HBASE-12740-v4.patch
Resubmitting since I see the previous patch was applied to master and retracted
by [~stack]. I guess the next version needs to be checked by HadoopQA :)

> 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.
