Vrushali C commented on MAPREDUCE-6424:
---------------------------------------

Need to ensure timeline metrics are emitted periodically as the app is running not just at completion.

> In MAPREDUCE-6327, we make map/reduce counters get encoded from JobFinishedEvent as timeline events with counters details in JSON format. 
> We need to store framework specific counters as metrics in timeline service to support query, aggregation, etc.
