------------------------------
Summary: Avoid to create watcher without the resourceVersion
Key: FLINK-27925
URL: https://issues.apache.org/jira/browse/FLINK-27925
Project: Flink
Issue Type: Improvement
Components: Deployment / Kubernetes
Reporter: Aitozi
Currently, we create the watcher in KubernetesResourceManager. But it do not
pass the resourceVersion parameter, it will read from the etcd. It will bring
the burden to the etcd in large scale cluster (which have been seen in our
internal k8s cluster). More detail can be found
[here|https://kubernetes.io/docs/reference/using-api/api-concepts/#the-resourceversion-parameter]
I think we could use the informer to improve it (which will spawn a list-watch
and maintain the resourceVersion internally)
