Subject [jira] [Created] (MAPREDUCE-3380) JobClient.getDelegationToken() returns NULL
Date Wed, 09 Nov 2011 01:13:51 GMT
JobClient.getDelegationToken() returns NULL
-------------------------------------------

                 Key: MAPREDUCE-3380
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3380
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am
    Affects Versions: 0.23.0
            Reporter: Alejandro Abdelnur
            Priority: Blocker
             Fix For: 0.23.1


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)
