Sample Hadoop test using HDFS and MiniKDC

[Kevin Minder]

Hey Everyone,
I ran across this test in Hadoop the other day.
https://github.com/apache/hadoop/blob/2f623fb8cc3dc49221216c3b46b6f51144811904/hadoop-hdfs-project/hadoop-hdfs/src/test/java/org/apache/hadoop/hdfs/qjournal/TestSecureNNWithQJM.java
I was thinking it could be the bases for a secure functional test.  We are 
sorely missing those.  My basic thought would be that this type of test would 
have a separate maven profile and would run as a separate jenkins job.
Kevin.
