>
> Need a new server side option to enable getting delegation tokens from
> ATS (Application Timeline Server - generic history server for YARN Apps) for
> tez jobs. Putting yarn.timeline-service.enabled=true in yarn-site.xml will
> enable it for mapreduce jobs as well which is not needed. There are fixes
> being done in future releases of YARN and TEZ to not fail but just warn and
> proceed if they could not talk to ATS server. Since that is not available
> now and ATS is not stable yet in Hadoop 2.6, it is preferable to use it only
> for Tez jobs and not impact mapreduce jobs as jobs will fail if ATS token
> could not be fetched.
