>                 URL: https://issues.apache.org/jira/browse/TEZ-340
>             Project: Apache Tez
>          Issue Type: Improvement

> 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.
