[jira] [Updated] (HADOOP-8043) KerberosAuthenticationFilter and
friends have some problems
[ 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.
