Subject [jira] [Commented] (YARN-6936) [Atsv2] Retrospect storing entities into sub application table from client perspective
Date Wed, 04 Apr 2018 06:27:00 GMT

Vrushali C commented on YARN-6936:
----------------------------------

Haibo, Rohith and I had a discussion on this over hangouts. I think we are in agreement on
the approach and the patch overall looks like it aligns with our discussion. But we will review
the patch once again tomorrow and proceed. We chatted briefly about YARN-3401 since we need
to think about entity types and evaluate who can write what entities.

> Currently YARN-6734 stores entities into sub application table only if doAs user and
submitted users are different. This holds good for Tez kind of use cases. But AM runs as same
as submitted user like MR also need to store entities in sub application table so that it
could read entities without application id. 
> This would be a point of concern later stages when ATSv2 is deployed into production.
This JIRA is to retrospect decision of storing entities into sub application table based on
client side configuration driven rather than user driven.
