Daryn Sharp commented on HDFS-1805:
-----------------------------------
This test is quite problematic. A similar problem is that the storage
directory isn't being properly reset, apparently even by a nn reformat, which
can often lead to odd test failures until the directory is manually deleted.
Running the test after a failure can lead to errors about unable to lock the
storage directory -- perhaps this is the original issue?
> Some Tests in TestDFSShell can not shutdown the MiniDFSCluster on any
> exception/assertion failure. This will leads to fail other testcases.

> If any test assertion failure or exception can result in not shutting down

> difficulty in finding the actual testcase failures.
> So, better to shutdown the cluster in finally.
