All Implemented Interfaces:

KubernetesStepDecorator

public class InternalServiceDecorator
extends AbstractKubernetesStepDecorator

Creates an internal Service which forwards the requests from the TaskManager(s) to the active JobManager. Note that only the non-HA scenario relies on this Service for internal communication, since in the HA mode, the TaskManager(s) directly connects to the JobManager via IP address.
