-------------------------------------
Resolution: Won't Fix
In ATSv2 weekly call, discussed for cleaning up JIRA which are not going
implement. Hence, closing the JIRA as Won't Fix. Feel free to reopen if still
same design approach exists.
> [Aggregation] Application/Flow/User/Queue Level Aggregations

> Key: YARN-3815
> URL: https://issues.apache.org/jira/browse/YARN-3815
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Reporter: Junping Du
> Assignee: Junping Du
> Priority: Critical
> Labels: YARN-5355
> Attachments: Timeline Service Nextgen Flow, User, Queue Level
> Aggregations (v1).pdf, aggregation-design-discussion.pdf,
> hbase-schema-proposal-for-aggregation.pdf

>
> Per previous discussions in some design documents for YARN-2928, the basic
> scenario is the query for stats can happen on:
> - Application level, expect return: an application with aggregated stats
> - Flow level, expect return: aggregated stats for a flow_run, flow_version
> and flow
> - User level, expect return: aggregated stats for applications submitted by
> user
> - Queue level, expect return: aggregated stats for applications within the
> Queue
> Application states is the basic building block for all other level
> aggregations. We can provide Flow/User/Queue level aggregated statistics info
> based on application states (a dedicated table for application states is
> needed which is missing from previous design documents like HBase/Phoenix
> schema design).
