Not supported as of now. There are multiple aspects to supporting this properly. One of the most important issues to address would be to do proper QoS across various DAGs i.e. what kind of policies would need to be built out to run multiple DAGs to completion within a limited amount of resources. The model would become close to a mini-jobtracker or a spark-standalone cluster.
