> 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.
