Re: HDFS Test Failure
Nope, doesn't work. Doing 'mvn clean install' still gives me errors on the
HDFS mini cluster test; doing an install without tests and then running
'mvn test' doesn't work either.

Running the tests with sudo generates the same results as before: HDFS
tests work, but TestAsyncHBaseSink / TestHBaseSink end up timing out.
