Did you run that exact file with PySpark? The important bits are that
namedtuple is imported and an instance is created before any PySpark imports,
and we launch a job that tries to serialize a namedtuple in its function
closure, and this serialization takes place before the hack is registered
(hence my use of text file instead of parallelize).
