Li Lu commented on MAPREDUCE-6424:
----------------------------------

I'm looking into the test failure. Right now I found a timing issue for 
aggregations, but unfortunately this is not the root cause of the UT failure 
(those two components appear to be independent). Will keep looking into this 
issue. [~Naganarasimha] if you have time would you please also try to reproduce 
the problem? Thanks!

> 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.
