             Summary: determine how to generate YARN container events
                 Key: YARN-3616
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: YARN-2928
            Reporter: Sangjin Lee

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.
