Description

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.
