[jira] [Created] (FLINK-16717) Use headless service for rpc and blob port when flink on K8S

vanderliang created FLINK-16717:
-----------------------------------

             Summary: Use headless service for rpc and blob port when flink on K8S
                 Key: FLINK-16717
                 URL: https://issues.apache.org/jira/browse/FLINK-16717
             Project: Flink
          Issue Type: Improvement
          Components: Deployment / Kubernetes
    Affects Versions: 1.10.0
         Environment: flink 1.10
            Reporter: vanderliang


Current, when submitting a flink job cluster on kubernetes, the [https://github.com/apache/flink/blob/release-1.10/flink-container/kubernetes/job-cluster-service.yaml] will create Node Port type service for all ports. 

First, the RPC and blob only need a headless service which could avoid iptables or ipvs forwarding. 

Second，serverless K8S(like AWS EKS) in public cloud does not support Node Port，which cause some problem when running flink On serverless K8S.
