             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
            Reporter: Junping Du

We need flow/user level aggregation to present flow/user related states to end users.
Flow level aggregation involve three levels aggregations:
- The first level is Flow_run level which represents one execution of a flow and shows exactly aggregated data for a run of flow.
- The 2nd level is Flow_version level which represents summary info of a version of flow.
- The 3rd level is Flow level which represents summary info of a specific flow.

User level aggregation represents summary info of a specific user, it should include summary info of accumulated and statistic means (by two levels: application and flow), like: number of Flows, applications, resource consumption, resource means per app or flow, etc.
