Yang Wang commented on FLINK-17566:
-----------------------------------
Great. Bumping the fabric8 kubernetes-client version to 4.9.1 could solve this
problem. I have verified the application mode with multiple times. It always
works well.
> 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
> Priority: Major
>
> 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
>
