Russell Jurney commented on PIG-2529:
-------------------------------------
This is a good opportunity to move piggybank to github. Python UDFs can go
here: https://github.com/wilbur/Piggybank/tree/master/src/main/python
Fork and clone the project, submit a pull request with a test, and your python
udf is in piggybank.
> Creation of a Python PiggyBank
> ------------------------------

> Key: PIG-2529
> URL: https://issues.apache.org/jira/browse/PIG-2529
> Project: Pig
> Issue Type: New Feature
> Components: piggybank
> Reporter: Eli Finkelshteyn
> Priority: Minor
> Labels: piggybank, python
>
> As per a conversation on the Pig user list, I think it makes sense to create
> a PiggyBank for Python functions. To get us started, here's something short
> and quick I wrote to convert a bag of single item tuples to one single tuple:
> @outputSchema("t:tuple()")
>
> def bagToTuple(bag):
>
> t = tuple([item[0] for item in bag])
>
> return t
