> we hit HBASE-6031 again, after looking into thread dump, it was caused by the
> threads from QueuedThreadPool are user thread, not daemon thread, so the
> hbase shutdownhook never be called and the hbase instance was hung.
> Furthermore, i saw daemon be set in fb-20 branch, let's set in trunk codebase
> as well, it should be safe:)
