Subject [jira] [Commented] (MAPREDUCE-5199) AppTokens file can/should be removed
Date Thu, 16 May 2013 17:19:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13659730#comment-13659730

Vinod Kumar Vavilapalli commented on MAPREDUCE-5199:

Looking at the patch. But I don't understand the problem, but not discounting that there isn't
any problem at all.

bq. MAPREDUCE-5205 fixed the AM to pick up the app token, but jobs launching jobs (ex. oozie)
still fail. The child job reads in the appTokens file generated by the parent job which causes
the child to overwrite the app token with that of the parent job.
I don't understand this. AMRMToken is never part of the appTokens files. Where is the child
job failing? Can you share some exception traces?
