Uma Maheswara Rao G commented on HDFS-2531:
-------------------------------------------
Yes Aaron, you are right. If we specify fork option, it will spawn separate JVM.
As Todd pointed, TestDfsOverAvroRpc would be the real cause for test failures.
This can be consider to ensure correct pattern in tests. When we add any new
tests need not change others.
> TestDFSClientExcludedNodes is failing in trunk.
