Subject [jira] [Updated] (MAPREDUCE-3380) Token infrastructure for running clients which are not kerberos authenticated
Date Fri, 06 Jan 2012 22:48:39 GMT

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

Mahadev konar updated MAPREDUCE-3380:
-------------------------------------

    Attachment: MAPREDUCE-3380.patch

Finally was able to get a secure oozie running and test this patch out. The patch works. The
only issue is that oozie still reports the job as running although the launcher and action
job complete. Will have to debug that with some oozie folks but as for the token this should
be it.

> 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)
