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.

> This proposes to create secured Mini*Clusters by incorporating MiniKdc to test in Kerberos mode. Would be good to provide common wrapper of MiniKdc with useful facilities for kinds of Mini*Clusters like MiniDFSCluster, MiniYARNCluster and etc, and such wrapper should be very easy to be incorporated into target Mini*Cluster.
