@cnauroth there are still 2 test failures and they seem genuine (not
intermittent failures).
I might need someone with more HDFS debugging experience than me to look
into this one.
This test just timeouts waiting for a name-node restart. Something behind
the scenes is failing and not logging anything.

Likewise, the mapreduce test failure has no obvious cause.
