Aaron T. Myers updated HDFS-2952:
---------------------------------

    Attachment: HDFS-2952-HDFS-1623.patch

Thanks a lot for the review, Todd.

I realized upon taking another look at the patch that I forgot to shutdown the 
mini clusters used in this patch. It shouldn't matter, since the tests are 
designed to assert that the clusters don't start, but in the event the clusters 
do start, it still seems best to shutdown the clusters. Here's an updated patch 
which does that. I'm going to commit it since it's a pretty trivial change 
since the last patch.
