-------------------------------------
I'm seeing this too, today, OS/X, my lifecycle enhanced branch

Interesting elapsed time, just over a minute, that's the kind of
spin-for-over-a-minute kind of situation that usually implies some timeout has
happened but not fed upwards.

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: name-node
> Affects Versions: 0.21.0
> Environment: 64-bit debian 5, 64-bit sun java6, running in a single
> processor VM.
> Reporter: Eli Collins

> 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.
