Harish Jaiprakash created TEZ-3611:
--------------------------------------

             Summary: Create lightweight summary events for ATS.
                 Key: TEZ-3611
                 URL: https://issues.apache.org/jira/browse/TEZ-3611
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Harish Jaiprakash
            Assignee: Harish Jaiprakash


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.
