we got python 3.4 installed and is there a way to have pig use 3.4 as default python instead of 2.6?

You need to update the pig.properties value to be like the below to force it to use a different python alias when using the new Pig 13+ Python Streaming functions:

pig.streaming.udf.python.command=python3

Are you talking about running a Pig UDF written in Python? You need to make sure you are using streaming_python instead of jython. What does your REGISTER command look like?

Adding that setting is not really working for me, I'm doing something like this

register 's3://fernandos-tests/python-udfs/python-version.py' using streaming_python as pyudfs;
...
results = FOREACH limited GENERATE pyudfs.version();

DUMP results;

My python code looking like...

from pig_util import outputSchema

import sys

@outputSchema('word:chararray')
def version():
    return sys.version

And still getting python version 2.7

Any hints?
