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

[~trohrmann] [~yittg] I can't submit batch jobs more than almost 60, I submitted one job every
5 minutes if it is watching connection is exhausted.  did the connection did not release to
pool when one batch job is closed?

>             Project: Flink
>          Issue Type: Improvement
>          Components: Runtime / Coordination
>    Affects Versions: 1.12.2, 1.13.0
>            Reporter: Yi Tang
>            Assignee: Yi Tang
>            Priority: Major

>             Fix For: 1.14.0

> While using K8s HA service, the watching for ConfigMap is separate for each job. As the
number of running jobs increases, this consumes a large amount 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.
