------------------------------
Resolution: Duplicate
> Observer should detect flink job even if deployment status is empty
> -------------------------------------------------------------------
>
> Key: FLINK-26345
> URL: https://issues.apache.org/jira/browse/FLINK-26345
> Project: Flink
> Issue Type: Improvement
> Components: Kubernetes Operator
> Reporter: Gyula Fora
> Priority: Major
> Fix For: kubernetes-operator-1.0.0
>
>
> Currently it is possible to get into a cornercase where the job is submitted
> by the reconciler but the deployment status is not updated to reflect the
> submission.
> In these cases the observer does not attempt to "recover" the cluster, it
> simply skips the observation step, thinking that the job is not running
> (status == null).
> However this means that the reconciler will try to submit it again leading to
> the error:
> {code:java}
> org.apache.flink.client.deployment.ClusterDeploymentException: The Flink
> cluster job-name already exists.
