> It looks like the issue is with serializing random(). If you remove random() from the function then everything works fine.
> I'm just running PYSPARK_PYTHON=//home/tgraves/pypy-my-own-package-name/bin/pypy ./bin/pyspark
> I've tried multiple versions of pypy from 2.5.1 to 5.8.0. I tried the portable version as well as built pypy from source.
> If it works for others perhaps I have a setup issue, any hints on that would be appreciated.
