[GitHub] [flink] tillrohrmann commented on pull request #14692: [FLINK-20944][k8s] Do not resolve the rest endpoint address when the service exposed type is ClusterIP

   The idea of the address resolution was to check that the client can actually talk to the cluster and to fail early if this is not the case. Hence, I am not sure whether we should change this behaviour because it can lead to the following problem: Let's assume we deploy a per-job cluster with `ClusterIP`. Then it is not possible for the client to talk to the cluster and, consequently, we will never fetch the final result of the job which is required for shutting the cluster down. Hence, the user should either deploy the cluster in detached mode or from within the K8s cluster. Everything else should fail.
