Date Wed, 10 Feb 2016 16:56:18 GMT

    [ https://issues.apache.org/jira/browse/YARN-4682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15141162#comment-15141162

Prabhu Joseph commented on YARN-4682:


  Steve, do i need to checkout branch-2. 

The issue "No AMRMToken" happened on hadoop-2.4.1. So like you mentioned, the fix of  YARN-3103
and YARN-2212 is missing there. I am doing a testing with the YARN-3103 fix, for every yarn.resourcemanager.am-rm-tokens.master-key-rolling-interval-secs,
the AMRMToken gets updated. How to decrease the life time of a token, trying to simulate the
issue again.
