UDFs in non Java languages

[Asif Jan <as...@gmail.com>]

Hi

I read on the wiki that further developments will be carried out allowing users to write their UDFs in other languages. I am specifically interested in being able to use R functions in Pig.

Also, if python (instead of jython) UDFs are implemented then one could benefit from a range of libraries such as NumPy and SciPy.

How could I find further information on the subject.

thanks

Another option might be something like renjin
(http://code.google.com/p/renjin/).  I've not used it though, so
unfortunately I can't vouch for its feature set/capabilities.

Asif,
Pig can only work with JVM-based languages (so, Jython for python and Rhino
for javascript).
You can use streaming to process data using R or non-jvm python versions.
