Zhihong Yu commented on HBASE-5975:
-----------------------------------

I applied patch from HBASE-5966.
I saw this failure:

I think Jonathan H. is working on the above issue in HBASE-5876.

> Unit test failed with error:  Failed suppression of fs shutdown hook
> ShutdownHookManager.deleteShutdownHook failed to delete the hook since it should be runnable
instead of a thread for HADOOP 2.0.0.
> For other HADOOP version, runnable should work too since thread implements runnable.
