--------------------------------
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.).
