Zhijie Shen commented on YARN-3040:

[~sjlee0], thanks for more comments, but would you mind continuing the flow 
attributes discussion in YARN-3391 to unblock this jira? In this jira, how 
about focusing on the data flow to passing this context info to the collector? 
For flow info, no matter what it should be specifically, this patch works out 
the path to collect it from user via application submission context and pass it 
to RM, NM and finally to the collector. If we're okay with is approach. It is 
easy for us to add new flow info or correct existing flow info later on. I 
filed YARN-3391 to fork the flow related discussion.

> Per design in YARN-2928, implement client-side API for handling *flows*. 
> Frameworks should be able to define and pass in all attributes of flows and 
> flow runs to YARN, and they should be passed into ATS writers.
> YARN tags were discussed as a way to handle this piece of information.
