> [FlinkKubeClient.checkAndUpdateConfigMap|https://github.com/apache/flink/blob/ab3eb40d920fa609f49164a0bbb5fcbb3004a808/flink-kubernetes/src/main/java/org/apache/flink/kubernetes/kubeclient/FlinkKubeClient.java#L163]
> expects an error to be forwarded through the {{CompletableFuture}} instead
> of throwing a {{RuntimeException}}.
> The actual implementation implements it accordingly in
> [Fabric8FlinkKubeClient:313|https://github.com/apache/flink/blob/025a95b627faf8ec8b725a7784d1279b41e10ba7/flink-kubernetes/src/main/java/org/apache/flink/kubernetes/kubeclient/Fabric8FlinkKubeClient.java#L313]
> where a {{CompletionException}} is thrown within the {{CompletableFuture}}'s
> {{supplyAsync}} call resulting the future to fail.
> {{KubernetesTestFixture}} doesn't make the returned future complete
> exceptionally but throws a {{CompletionException}} (see
> [KubernetesTestFixture:172|https://github.com/apache/flink/blob/6fc5f789869433688eb5f62494f1a4404e0dd11b/flink-kubernetes/src/test/java/org/apache/flink/kubernetes/highavailability/KubernetesTestFixture.java#L172]).
> This results in inconsistent test behavior.
