Ravi Prakash commented on HDFS-6823:
------------------------------------

Patch looks good to me. +1. The unit test failure is unrelated. It fails on an unpatched build as well. HDFS-4663 is open (although for an OOM, I don't think it makes sense to create another JIRA.)

Will commit shortly. Thanks Allen!

> If Kerberos isn't configured, we shouldn't try to display the principal message, never mind the raw text of the configuration option.
