Hi Chris,

Thanks for your great info. I would paste it in the JIRA for future reference if I or somebody
else get the chance to work on it.

Hi David and Kai,

There are a couple of challenges with this, but I just figured out a pretty decent setup while
working on HDFS-2856.  That code isn't committed yet, but if you open patch version 5 attached
to that issue and look for the TestSaslDataTransfer class, then you'll see how it works. 
Most of the logic for bootstrapping a MiniKDC and setting up the right HDFS configuration
properties is in an abstract base class named SaslDataTransferTestCase.

I hope this helps.

There are a few other open issues out there related to tests in secure mode.  I know of HDFS-4312
and HDFS-5410.  It would be great to get more regular test coverage with something that more
closely approximates a secured deployment.
