> Currently, if we start a native K8s session cluster with 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.
