-----------------------------------------

Ok, will have a look at this in my patch tomorrow as its quite late here now.
Moreover, we need to decide if we want to split configs right now and if yes is 
an approach based on size configuration or a internal fixed value fine ?

> Store MR counters as timeline metrics instead of event

> 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.
