[jira] [Created] (YARN-8038) Support data retention policy in YARN ATSv2

Haibo Chen created YARN-8038:
--------------------------------

             Summary: Support data retention policy in YARN ATSv2
                 Key: YARN-8038
                 URL: https://issues.apache.org/jira/browse/YARN-8038
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: timelineservice
    Affects Versions: 3.0.0
            Reporter: Haibo Chen


The data stored today in ATSv2 is either system data in that it is generated by YARN, or custom data that is generated by Application Masters themselves.

Data retention policy is necessary to maintain feature parity between the new MR JHS with the current JHS.

We may want to provide separate policies for system data and custom data.
