             Summary: Support for submitting DAGs that reference existing DAGs in a session
                 Key: TEZ-3047
                 URL: https://issues.apache.org/jira/browse/TEZ-3047
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Bikas Saha
            Assignee: Bikas Saha


Another example of supporting DAG modifications would be to be able to support a new DAG in a session that reuses intermediate outputs from a previous DAG. If 2 DAGs are such that a sub-part of DAG1 can be reused as a sub-part of DAG2 then DAG2 could potentially avoid re-running part of itself by connecting itself to an vertex in DAG1.
