             Summary: Support storing sub-application entities
                 Key: YARN-6733
                 URL: https://issues.apache.org/jira/browse/YARN-6733
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Vrushali C
            Assignee: Vrushali C



After a discussion with Tez folks, we have been thinking over introducing a table to store  sub-application information.

For example, if a Tez session runs for a certain period as User X and runs a few AMs. These AMs accept DAGs from other users. Tez will execute these dags with a doAs user. ATSv2 should store this information in a new table perhaps called as "sub_application" table. 

This jira tracks the code changes needed for  table schema creation.

I will file other jiras for writing to that table, updating the user name fields to include sub-application user etc.
