[jira] [Created] (FLINK-22006) Could not run more than 20 jobs in a native K8s session with K8s HA enabled

Yang Wang created FLINK-22006:
---------------------------------

             Summary: Could not run more than 20 jobs in a native K8s session with K8s HA enabled
                 Key: FLINK-22006
                 URL: https://issues.apache.org/jira/browse/FLINK-22006
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.12.2, 1.13.0
            Reporter: Yang Wang

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.
