> 2018-09-26 15:32:31,732 WARN  org.apache.flink.runtime.dispatcher.DispatcherRestEndpoint    - Upload directory /var/folders/hr/cxn1_2y52qxf5nzyfq9h2scw0000gn/T/flink-web-2218b898-f245-4edf-b181-8f3bdc6014f3/flink-web-upload does not exist, or has been deleted externally. Previously uploaded files are no longer available.
> {code}
> I found this warning confusing as it is always logged when relying on the default configuration (via {{WebOptions}}) that picks a random directory.
> Ideally, our default configurations should not result in warnings to be logged.
> Therefore, I propose to log the creation of the web directory on {{INFO}} instead of the warning.
