--------------------------------
Summary: [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
Reporter: Junping Du
Assignee: Junping Du
Priority: Critical
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).
