Yi Tang commented on FLINK-22006:
---------------------------------
The watching for configMap is a little different from that for pods. The
watchings for configMap will start and go after the watching starts. I think we
should do something to keep the same semantic with watching separately.
Here [FLINK-22054] i create another issue to track the sharded ConfigMap
watcher proposal.

> Currently, if we start a native K8s session cluster when K8s HA enabled, we
> could not run more than 20 streaming jobs.
>
> The latest job is always initializing, and the previous one is created and
> waiting to be assigned. It seems that some internal resources have been
> exhausted, e.g. okhttp thread pool , tcp connections or something else.
