Ashutosh Chauhan commented on PIG-928:
--------------------------------------
Addendum:
* Also what will happen if user returned a nil python object (null equivalent
of Java) from UDF. It looks to me that will result in NPE. Can you add a test
for that and similar test case from pigToPython()
> UDFs in scripting languages

> It should be possible to write UDFs in scripting languages such as python,
> ruby, etc. This frees users from needing to compile Java, generate a jar,
> etc. It also opens Pig to programmers who prefer scripting languages over
> Java.
