com.actian.dataflow.cal.yarn.server.YarnClusterExecutor

All Implemented Interfaces:

DistributedExecutorService

public class YarnClusterExecutor
extends com.pervasive.datarush.cal.dr.AbstractDRClusterExecutor

The executor responsible for starting Dataflow worker containers within YARN. An executor is started by the cluster execution framework for every phase of a dataflow job. It is the executor's job to start and manage a container for every partition of a job. The executor is started within the application master and is invoked by the cluster execution framework as needed to manage containers.
