    Description

      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
