I think if you have a flink.Path() object, you can call getFileSystem() or
so on it.. The FileSystem class you're getting is abstracting from the actual
file system (remote, local).
If you are not adding a scheme prefix (file:/// or hdfs:///) it will
automatically use the local file system. I think the Path() thing is also able
to handle relative paths.
Maybe its a good idea to put these "temp" files into the home directory of
the user (".flink/python"). The YARN client is also doing it this way. You
should make sure to clean everything up afterwards.
