Import module in MRJob on EMR
===

Simple question: I have a module headers.py which defines a couple variables I need in my main MRJob script. I should be able to run the job with

    python MRMyJob -r emr --files=headers.py s3://input/data/path

and then in my MRJob script (MRMyJob), the following should work:

    from headers import header1, header2, header3

Right? From the mrjob --help page: "--file=UPLOAD_FILES
                        Copy file to the working directory of this script. You
                        can use --file multiple times."

I'm still getting "no module named headers" when I try to import it.
