             Summary: Using a shared watcher for ConfigMap watching
                 Key: FLINK-22054
                 URL: https://issues.apache.org/jira/browse/FLINK-22054
             Project: Flink
          Issue Type: Improvement
            Reporter: Yi Tang


While using K8s HA service, the watching for ConfigMap is separate for each job.

This will cost large amounts of connections.

Here we proposal to use a shard watcher for each FlinkKubeClient, and dispatch events to different listeners. At the same time, we should keep the same semantic with watching separately.
