We didn't see those with flink-kubernetes-operator 1.11.0.
It seems that the operator tries to reach a service based on the jobs name
inside the cluster.
Since I am using a session cluster here, it should be reaching out to it and
query for exception logs - am I wrong?
The service however doesn't exist (and never did), hence the error message.
