-----------------------------------------------------------
[~felixzheng] The Flink client will throw a {{ClusterDeploymentException}}
caused by {{KubernetesClientException}}. Do we really need to check this
limitation additionally? I think what we need to do is to clean up the residual
resources when the Flink client failed.

> Two Kubernetes Service will be created when a session cluster is deployed,
> one is the internal Service and the other is the rest Service, we set the
> internal Service name to the value of the _kubernetes.cluster-id_
> configuration option and then set the rest Service name to
> _${kubernetes.cluster-id}_ with a suffix *-rest* appended, said if we set the
> _kubernetes.cluster-id_ to *session-test*, then the internal Service name
> will be *session-test* and the rest Service name be *session-test-rest;*
> there is a constraint in Kubernetes that the Service name must be no more
> than 63 characters, for the current naming convention it leads to that the
> value of _kubernetes.cluster-id_ should not be more than 58 characters,
> otherwise there are scenarios that the internal Service is created
> successfully then comes up with a ClusterDeploymentException when trying to
> create the rest Service.
