Subject [jira] [Commented] (YARN-4126) RM should not issue delegation tokens in unsecure mode
Date Tue, 08 Sep 2015 16:47:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14735132#comment-14735132
] 

Allen Wittenauer commented on YARN-4126:
----------------------------------------

Is there any actual harm in returning a useless delegation token?  I know on the HDFS side
of the house, returning null tokens has been extremely beneficial in streamlining the code.

> ClientRMService#getDelegationToken is currently  returning a delegation token in insecure
mode. We should not return the token if it's in insecure mode.
