------------------------------------

             Summary: Fix potential K8s resources leak after JobManager finishes in Applicaion mode
                 Key: FLINK-17566
                 URL: https://issues.apache.org/jira/browse/FLINK-17566
             Project: Flink
          Issue Type: Bug
          Components: Deployment / Kubernetes
            Reporter: Canbin Zheng


FLINK-10934 introduces applicaion mode support in the native K8s setups., but as the discussion in [https://github.com/apache/flink/pull/12003|https://github.com/apache/flink/pull/12003,], there's large probability that all the K8s resources leak after the JobManager finishes except that the replica of Deployment is scaled down to 0. We need to find out the root cause and fix it.

This may be related to the way fabric8 SDK deletes a Deployment. It splits the procedure into three steps as follows:
 # Scales down the replica to 0
 # Wait until the scaling down succeed
 # Delete the ReplicaSet
