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

             Summary: [Aggregation] App-level Aggregation on entity tables
                 Key: YARN-3816
                 URL: https://issues.apache.org/jira/browse/YARN-3816
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Junping Du
            Assignee: Junping Du


We need application level aggregation of Timeline data:
- To present end user aggregated states for each application, include: resource (CPU, Memory)
consumption across all containers, number of containers launched/completed/failed, etc. We
need this for apps while they are running as well as when they are done.
- Also, framework specific metrics, e.g. HDFS_BYTES_READ, should be aggregated to show details
of states in framework level.
- Other level (Flow/User/Queue) aggregation can be more efficient to be based on Application-level
aggregations rather than raw entity-level data as much less raws need to scan (with filter
out non-aggregated entities, like: events, configurations, etc.).
