Hi Dexin, Unfortunately, Pig is on Jython 2.5, so you won't be able to use Python 2.7 modules.

You might give it a try: http://search-hadoop.com/m/BnZs3MmH5y/jython+2.7&subj=informational+getting+jython+2+7+b1+to+work Thanks, Cheolsoo On Wed, Jul 17, 2013 at 3:33 PM, Dexin Wang <[email protected]> wrote: > When I do Python UDF with Pig, how do we know which version of Python it is > using?
