Konstantin Shvachko updated HDFS-615:
-------------------------------------

    Fix Version/s: 0.21.0
         Priority: Blocker  (was: Minor)

Looks like this causes a real pain for people. Should probably be fixed for 0.21 as a release cannot go on with failed tests.

> I've hit the following failure two out of two times running "ant test" at rev 813587. This test doesn't appear to be failing on hudson. All other tests passed except TestHDFSFileSystemContract which timed out, so perhaps there's a race due to the test executing slowly.
