-----------------------------------
Summary: Don't log warning when creating upload directory
Key: FLINK-10441
URL: https://issues.apache.org/jira/browse/FLINK-10441
Project: Flink
Issue Type: Improvement
Components: REST
Reporter: Ufuk Celebi
{{RestServerEndpoint.createUploadDir(Path, Logger)}} logs a warning if the
upload directory does not exist.
{code}

org.apache.flink.runtime.dispatcher.DispatcherRestEndpoint - Upload

does not exist, or has been deleted externally. Previously uploaded files are
no longer available.

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.
