InternalServiceDecorator (Flink : Kubernetes 1.18.1-cp2 API)

java.lang.Object
- org.apache.flink.kubernetes.kubeclient.decorators.AbstractKubernetesStepDecorator
- - org.apache.flink.kubernetes.kubeclient.decorators.InternalServiceDecorator

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.
