[jira] Updated: (PIG-928) UDFs in scripting languages

["Dmitriy V. Ryaboy (JIRA)" <ji...@apache.org>]

Dmitriy V. Ryaboy updated PIG-928:
----------------------------------

    Attachment: PIG-928.patch

I rebased the patch and made it pull jython down via maven. 2.5.1 doesn't appear to be available right now, so this pulls down 2.5.0. Hope that's ok.

Looks like the tabulation is wrong in most of this patch.. someone please hit ctrl-a, ctrl-i next time :).

Needless to say, this thing needs tests, desperately.

Also imho in order for it to make it into trunk, it should be a compile-time option to support (and pull down) jython or jruby or whatnot, not a default option. Otherwise we are well on our way to making people pull down the internet in order to compile pig.

> 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.
