Zhijie Shen commented on YARN-3041:
-----------------------------------
bq. I think the run id of a flow is an attribute of a flow, it need not be a
separate class.
So what's the difference between flow and flow run? On page.5 of the design doc
v2, it seems that flow run is the child of flow. [~sjlee0], would you please
comment?
bq. Also, queue and user are timeline entities, I think if they may not require
a class by themselves.
Do you mean they need to extend timeline entity? I think in the new patch, they
do it in this way.
