Subject [jira] [Updated] (MAPREDUCE-3380) Token infrastructure for running clients which are not kerberos authenticated
Date Wed, 11 Jan 2012 00:38:40 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3380?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Vinod Kumar Vavilapalli updated MAPREDUCE-3380:

    Attachment: MAPREDUCE-3380-20120110.1.txt

+1 overall. Cleaned the patch a bit.
 - Adding extra check for Kerberos authentication when asking for delegation tokens
 - Reusing the same record DelegationToken for both RM side and JHS side tokens
 - Removed unnecessary changes to minimize the patch size and to make it tractable for review.
 - There may be better ways to populate the history related delegation tokens but the current
one to pass around info via conf should do the trick for now.

> The JobClient.getDelegationToken() method is returning NULL, this makes Oozie fail when
trying to get the delegation token to use it for starting a job.
> What is seems to be happing is that Jobclient.getDelegationToken() calls Cluster.getDelegationToken()
that calls YarnRunner.getDelegationToken() that calls ResourceMgrDelegate.getDelegationToken().
And the last one is not implemented. (Thanks Ahmed for tracing this in MR2 code)
