--------------------------------------
Hey Woody,
Great work !! This will definitely be useful for lot of Pig users. I just
hastily looked at your work. One question which stuck to me is you are doing
lot of heavy lifting to provide for multi-language support by figuring out
which language user is asking for and then doing reflection to load appropriate
interpreter and stuff. I think it might be easier to use one of the frameworks
here (BSF or javax.script) which hides this and allows handling of multiple
language transparently. (atleast, thats what they claim to do) Have you taken a
look at them? These frameworks will arguably help us to provide support for
more languages without maintaining lot of code on our part. Though, I am sure
they will come at the performance cost (certainly CPU and possibly memory too).

> 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.
