Yes, this is true, but the way it is implemented, the folders are not
always added to the class loader. Maybe I'm wrong here, but
JobWithJars.getUserCodeClassLoader and JobWithJars.buildUserCodeClassLoader
don't add the URLs to the ClassLoader that they create.
> Allow adding of URLs to the usercode class loader

> Issue Type: Improvement
> Components: Distributed Runtime
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Minor
>
> Currently, there is no option to add customs classpath URLs to the
> FlinkUserCodeClassLoader. JARs always need to be shipped to the cluster even
> if they are already present on all nodes.
> It would be great if RemoteEnvironment also accepts valid classpaths URLs and
> forwards them to BlobLibraryCacheManager.
