Subject [jira] [Commented] (HDFS-6823) dfs.web.authentication.kerberos.principal shows up in logs for insecure HDFS
Date Fri, 08 Aug 2014 18:19:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14091083#comment-14091083
] 

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.
