Subject [jira] [Commented] (YARN-4006) YARN ATS Alternate Kerberos HTTP Authentication Changes
Date Thu, 05 May 2016 01:53:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-4006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15271786#comment-15271786
] 

Greg Senia commented on YARN-4006:
----------------------------------

[~aw], I attached the sample ats code. It's intentionally not complete because its NOT secure
without a bunch of code that I had to strip due to it only working at my employers site but
I think it provides the general gist of the problem that exists here.
