Subject [jira] [Updated] (MAPREDUCE-3291) App fail to launch due to delegation token not found in cache
Date Fri, 04 Nov 2011 22:11:51 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3291?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Robert Joseph Evans updated MAPREDUCE-3291:

    Attachment: MR-3291.txt

The issue appears to be cause by MRv2 not supporting mapreduce.job.complete.cancel.delegation.tokens

I originally posted this patch to MAPREDUCE-3359 and got some feedback there on it.  The discussion
there had me post the patch here instead.
