Ido Hadanny commented on PIG-4124:
----------------------------------
[~msukmanowsky], [~cheolsoo] - sorry for reviving this after such a long time,
but I'm a big fan of installing python modules on virtualenvs and the shipping
them and using them in a python udf. This is the way I'm currently doing it:
https://ihadanny.wordpress.com/2014/12/01/python-virtualenv-with-pig-streaming/
. Can you recommend of an easier way to do it? can you share what you guys are
using? Or do you prefer I'll open a stack-overflow question about this?
Thanks!
> Command for Python streaming udf should be configurable

> In my cluster, multiple versions of python are installed such as python2.6,
> python2.7, etc. Since some modules are only available on non-default python
> versions, it would be nice if the python command could be configurable by the
> user.
> For eg, I have a streaming udf that imports pytz. It fails with the following
> error if it runs with {{python}}-
> {code}
> : Caused by: org.apache.pig.impl.streaming.StreamingUDFException: LINE 4:
> ImportError: No module named pytz
> : File

> line 4, in <module>
> : import pytz
> : at
> org.apache.pig.impl.builtin.StreamingUDF$ProcessErrorThread.run(StreamingUDF.java:519)
> {code}
> But it works if I use {{python2.7}} as command.
