Subject [jira] [Commented] (HADOOP-8043) KerberosAuthenticationFilter and friends have some problems
Date Thu, 09 Feb 2012 21:40:57 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204910#comment-13204910
] 

Allen Wittenauer commented on HADOOP-8043:
------------------------------------------

The Hadoop 1.0.0 release was shipped without that change, and that's what myself and others
are using.

If you have a better way to get the hostname (which may be a vip, so you can't cheat and just
ask for the local hostname!) associated with the service that opened the filter, feel free
to supply a better patch.
