Divya commented on TEZ-3820:
----------------------------
Thanks [~rohithsharma] for this. We are trying to use Tez with ATSv2 as well
and applied this patch now. As [~prabhujoseph] mentioned we do get null
pointer exception because we do not have call back handler at this point.
Tried creating Callback handler before this but DAG is not running/publishing
entities. Can i know if we made any further changes on this.
// assumption is at this point AMRMClient is created! So callback handler is
set to null TezAMRMClientAsyncProvider.createAMRMClientAsync(1000, null)
> Plugin to write history events to ATSv2

> YARN Timeline Service v.2 is the next major iteration of Timeline Server,
> following v.1 and v.1.5. ATSV.2 is created to address two major challenges of
> v.1 i.e Scalability and Usability improvements. Refer
> [ATSv2-doc|https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/TimelineServiceV2.html#Timeline_Service_v.2_REST_API]
> It would be nice to use ATSv2 for Tez which solves scalability problems.
