Review Comment:
Now it's hacky: The JAR will be added to SparkContect with a session UUID
prefix but will be accessible by all sessions (due to we wrapped it's
classloader).
On a second thought, I could make it cleaner by passing `default` as UUID
into the `sparkContext.addJar` method to explicitly disable isolation.
