> All DAG*Event are summary logs. DAGSubmittedEvent has dagPlan in it and 
> DAGFinishedEvent has counters in it. And hence these events very large, which 
> makes the dag landing page on the tez-ui very expensive.
> Split these events into two parts:
> * One which contains only data used by the tez-ui "All Dags" page which will 
> go into summary log.
> * Another which will contain the current object, which will be part of the 
> appropriate TimelineEntityGroupId.
