      Work Description: I've thrown this up on the Hadoop JIRA.  Now I'm blocked until someone reviews it, which might be Tom.

For my future reference, here's how you run the "test-patch" task on ant.  It takes a long time and spits out esoteric error messages.  (Turns out you need a block of the Apache license at the top of every file; who knew!)
{noformat}
ANT_HOME=/usr/share/ant ant -Dpatch.file=../hadoop-trunk2/HADOOP-5469.patch -Dforrest.home=$HOME/pub/apache-forrest-0.8 -Dfindbugs.home=$HOME/pub/findbugs-1.3.8 -Djava5.home=/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home -Dscratch.dir=/tmp/philip test-patch

I expect this will take some more time after the review.
