Xiaoyu Yao commented on HDFS-11463:
-----------------------------------

Thanks [~msingh] for working on this. The patch looks good to me, +1.

TestDatanodeStateMachine & TestCBlockServer seems to fail because some previous 
executed tests failed to clean up the cluster (e.g., delete directories, close 
the listening port). Can you file a separate ticket for fixing that? Thanks!
