Jason Lowe commented on YARN-3439:
----------------------------------
This appears to be caused by YARN-2704. YARN-2964 tried to fix it but assumed
that Oozie launcher jobs will always run for the duration of the sub-jobs.
This is true when the launcher runs a Pig job, but apparently is not true when
it runs a standard MapReduce job.
> RM fails to renew token when Oozie launcher leaves before sub-job finishes

> Key: YARN-3439
> URL: https://issues.apache.org/jira/browse/YARN-3439
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.7.0
> Reporter: Jason Lowe
> Assignee: Daryn Sharp
> Priority: Blocker
>
> When the Oozie launcher runs a standard MapReduce job (not Pig) it doesn't
> linger waiting for the sub-job to finish. At that point the RM stops
> renewing delegation tokens for the launcher job which wreaks havoc on the
> sub-job if the sub-job runs long enough for the tokens to expire.
