Todd Lipcon updated HDFS-827:
-----------------------------

    Attachment: hdfs-827.txt

Found this patch from long ago. This adds a set of unit tests for FSDataset (runs in about
a second).

There are a number of things I found suspicious in this test, marked with XXX. It's worth
looking into these to see if they represent bugs.

> FSDataset doesn't currently have a unit-test that tests it in isolation of the DN or
a cluster. A test specifically for this class will be helpful for developing HDFS-788
