public abstract class DagContainerLauncher
extends ContainerLauncher

Plugin to allow custom container launchers to be written to launch containers that want to support cleanup of DAG level directories upon DAG completion in session mode. The directories are created by the Tez Shuffle Handler (tez_shuffle). A typical implementation of dagComplete() method would contain logic to send http request(s) for dag deletion to the nodes that support this auxiliary service.
