Both the detached/attached mode for application, the submission process does not need to create a `RestClusterClient`. Currently, we only use the `RestClusterClient` to print the web monitor address in `KubernetesClusterDescriptor`. The problem is that Flink client does not know whether it is running in or out of the K8s cluster. So it is hard to not create the `RestClusterClient` and tell the users that they should not use the `flink cancel/list` out of the K8s cluster when using `ClusterIP` setting. Maybe we could add a log to remind users that the rest endpoint(e.g. webui, cancel, list, etc.) could only be used in the K8s cluster when service is exposed with `ClusterIP`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
