Subject [jira] [Created] (TEZ-340) Allow new DAG plans to be submitted via client to AM RPC

------------------------------

             Summary: Allow new DAG plans to be submitted via client to AM RPC
                 Key: TEZ-340
                 URL: https://issues.apache.org/jira/browse/TEZ-340
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Bikas Saha
            Assignee: Bikas Saha


The DAG AM currently expects the DAG plan to be available during AM launch. Enhancing this
to allow more DAG's to be sent to a currently running AM can help the same AM be used to multiple
small queries. This increases the possibility of re-using more resources and allows drill
down queries to be made more efficient. The first approach would run the different DAG's sequentially
and require them to be from the same user.
