Class RemoteExecutor

java.lang.Object

org.apache.flink.api.common.PlanExecutor

org.apache.flink.client.RemoteExecutor

public class RemoteExecutor
extends PlanExecutor

The RemoteExecutor is a PlanExecutor that takes the program and ships it to a remote Flink cluster for execution.

The RemoteExecutor is pointed at the JobManager and gets the program and (if necessary) the set of libraries that need to be shipped together with the program.

The RemoteExecutor is used in the RemoteEnvironment to remotely execute program parts.
