table
Key: YARN-3817
URL: https://issues.apache.org/jira/browse/YARN-3817
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelineserver
Reporter: Junping Du
Assignee: 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.
