Javascript UDFs don't work in local mode? At all?
Cross posting in hopes a user has this working...

Has anyone gotten JavaScript UDFs working in pig 0.10.0? The hello world
example doesn't work. I added debug to the code, and the rhino class
doesn't seem to be in the path? I tried installing rhino and including it
and that doesn't help.

Wtf mate? :)

I am loading 'test.js' in my script exactly as in the documentation for Pig
0.10, and the file contains the pasted example Javascript UDFs and I get:
