-----------------------------------

Hi Jaimin, Jitendra. I tried to run this test case, but it doesn't seem to work here:

todd@todd-w510:~/git/hadoop-common/hadoop-hdfs-project/hadoop-hdfs$ mvn test -PstartKdc -DstartKdc=true
-Dtest=TestSecureNameNode
...
Tests in error: 
  testName(org.apache.hadoop.hdfs.server.namenode.TestSecureNameNode): Failed on local exception:
java.io.IOException: Couldn't setup connection for nn1/localhost@EXAMPLE.COM to nn1/localhost@EXAMPLE.COM;
Host Details : local host is: "todd-w510/127.0.0.1"; destination host is: ""todd-w510":40329;


The test logs show:
2012-03-30 13:39:06,611 ERROR security.UserGroupInformation (UserGroupInformation.java:doAs(1208))
- PriviledgedActionException as:nn1/localhost@EXAMPLE.COM (auth:KERBEROS) cause:java.io.IOException:
Couldn't setup connection for nn1/localhost@EXAMPLE.COM to nn1/localhost@EXAMPLE.COM


Am I making a mistake in the invocation above? Looking at the actual users.ldif file, I don't
see how this can work on any machine which actually has a configured hostname other than localhost,
since the principals are inserted with "localhost" hostnames rather than something dynamically
generated based on the actual hostname.
