             Summary: Flink Kubernetes Operator docs lacks info on FlinkSessionJob submission
                 Key: FLINK-35892
                 URL: https://issues.apache.org/jira/browse/FLINK-35892
             Project: Flink
          Issue Type: Improvement
          Components: Kubernetes Operator
    Affects Versions: kubernetes-operator-1.9.0
            Reporter: Sergey Kononov


Hello,

After FLINK-26808 fix a job submission to Flink session cluster via Flink Kubernetes Operator (FKO) is still impossible without setting config option web.submit.enable to true. If it's false FKO produces an exception:

{{i.j.o.p.e.ReconciliationDispatcher [ERROR][fko/jobname] Error during event processing ExecutionScope\{ resource id: ResourceID{name='jobname', namespace='fko'}, version: 173807615} failed.}}
{{org.apache.flink.kubernetes.operator.exception.ReconciliationException: java.util.concurrent.ExecutionException: org.apache.flink.runtime.rest.util.RestClientException: [POST request not allowed]}}

As I understand it is an intended behavior as FKO uses {{/jars/*}} REST endpoints to submit jobs to a session cluster and they are not initialized if web.submit.enable is false.

I would suggest to mention in FKO docs ([here|https://github.com/apache/flink-kubernetes-operator/blob/main/docs/content/docs/custom-resource/overview.md#flinksessionjob-spec-overview[]|https://github.com/apache/flink-kubernetes-operator/blob/main/docs/content/docs/custom-resource/overview.md#flinksessionjob-spec-overview]) that the option web.submit.enable should be set to true if one intends to use FKO with the session cluster. I lost quite a lot of time to figure this out.

 

Best regards,

Sergey
