> When running Flink on Kubernetes, the stdout logs is not redirected to files so it will not shown in WEB UI. This is as expected.
> But It returns “500 Internal error” in REST API and produces an error log in jobmanager.log. This is confusing and misleading.
>  
> I think this API should return “404 Not Found” without any error logs, similar to how jobmanager/stdout works.
