Kumar Ravi commented on HBASE-6945:
-----------------------------------
Following is a comment I added in HBASE-6965. Although related, I believe these
are two separate issues. HBASE-6965 introduces a new Utility Bean class. This
issue uses the new Bean class in a Junit Test case.
Please let me know if you have further questions.
Thanks!

This was tested on Sun (Oracle) JDK 6 (1.6.0_34), OpenJDK 6 and IBM Java 7. All
tested on RHEL 6.3.

We borrowed this idea from the code here in hadoop:
http://svn.apache.org/repos/asf/hadoop/common/tags/release-1.0.3/src/core/org/apache/hadoop/security/UserGroupInformation.java.
See methods getOSLoginModuleName() - Line 262 and getOsPrincipalClass() - Line
276.
