Sangjin Lee commented on YARN-3461:
-----------------------------------
Posted patch v.1.
I am proposing essentially the original default proposal again as in the
[design
document|https://issues.apache.org/jira/secure/attachment/12691416/ATSv2.rev2.pdf].
Namely,
- flow name: the YARN app name (or the app id if the YARN app name is not set)
- flow version: "1"
- flow run id: the YARN app start time
I think this will cover most of the important use cases (e.g. old MR jobs that
do not specify flows) and keep things simple enough. What Junping suggested
above sounds reasonable and may add value for certain cases. However, I think
there is something to be said about keeping things simple at this point. We
could consider making this more configurable if such a need is identified later.
Let me know what you think. Also a review is greatly appreciated. Thanks!
