Uma Maheswara Rao G commented on HDFS-2531:
-------------------------------------------
This problem will come when some tests are still having the locks on storage
directories.
Looks the failures are random.
TestDFSClientExcludedNodes is not shotting down the cluster, so the next test
will fail diffinitely.
To find the cause for TestDFSClientExcludedNodes failure, need to check other
test where they are not shutting down the cluster.
> TestDFSClientExcludedNodes is failing in trunk.
