Subject [jira] [Commented] (HADOOP-10322) Add ability to read principal names from a keytab
Date Tue, 04 Mar 2014 21:41:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13920060#comment-13920060

Daryn Sharp commented on HADOOP-10322:
--------------------------------------

Yes, Allen, the main purpose of this patch is to support multiple keytab logins for multi-interface
support.

I think it might be better to add this to common's {{SecurityUtil}} so we can add multi-interface
support to other parts of hadoop.  For simplicity, I'd suggest a single method that takes
a path and pattern, then returns all the matching principals.
