>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: resourcemanager
>    Affects Versions: 2.6.0

> The RM used to globally track the unique set of tokens for all apps.  It 
> remembered the first job that was submitted with the token.  The first job 
> controlled the cancellation of the token.  This prevented completion of 
> sub-jobs from canceling tokens used by the main job.
> As of YARN-2704, the RM now tracks tokens on a per-app basis.  There is no 
> notion of the first/main job.  This results in sub-jobs canceling tokens and 
> failing the main job and other sub-jobs.  It also appears to schedule 
> multiple redundant renewals.
> The issue is not immediately obvious because the RM will cancel tokens ~10 
> min (NM livelyness interval) after log aggregation completes.  The result is 
> an oozie job, ex. pig, that will launch many sub-jobs over time will fail if 
> any sub-jobs are launched >10 min after any sub-job completes.  If all other 
> sub-jobs complete within that 10 min window, then the issue goes unnoticed.
