Subject [jira] [Updated] (HADOOP-8043) KerberosAuthenticationFilter and friends have some problems
Date Thu, 09 Feb 2012 03:14:10 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8043?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Allen Wittenauer updated HADOOP-8043:
-------------------------------------

    Attachment: HADOOP-8043-branch-1.0.txt

This patch is based upon my local git tree, so may not apply to yours.  But in any case it
does the following:

1. Updates the documentation
2. Adds support for signature.secret.file which is used in preference to signature.secret
(if both exist)
3. Adds support for _HOST in the principal name

I've only run this on a single test node, with the outstanding issue I've found being the
JT not wanting to auth for some reason.  I'm not sure if this is a filter issue or a JT issue,
however.
