Sangjin Lee commented on YARN-3616:
-----------------------------------
Yes, I agree that we should emit some events from RM that NM cannot handle. I
think we just need to enumerate clearly what events will be emitted by RM so
there is no duplication.
> determine how to generate YARN container events

> Key: YARN-3616
> URL: https://issues.apache.org/jira/browse/YARN-3616
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Affects Versions: YARN-2928
> Reporter: Sangjin Lee
> Assignee: Naganarasimha G R
>
> The initial design called for the node manager to write YARN container events
> to take advantage of the distributed writes. RM acting as a sole writer of
> all YARN container events would have significant scalability problems.
> Still, there are some types of events that are not captured by the NM. The
> current implementation has both: RM writing container events and NM writing
> container events.
> We need to sort this out, and decide how we can write all needed container
> events in a scalable manner.
