Sangjin Lee commented on YARN-3041:
-----------------------------------

LGTM. Thanks for reflecting the latest feedback!

I agree with your points for the most part. The update of the design doc is 
long overdue. I'll try to update the document to reflect all the changes that 
have taken place so far.

We'll file more JIRAs if we need to adjust/update the data model as the work 
progresses.

> Also, as part of this JIRA, create YARN system entities (e.g. cluster, user, 
> flow, flow run, YARN app, ...).
