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