Subject [jira] [Commented] (PIG-2317) Ruby/Jruby UDFs
Date Tue, 27 Mar 2012 16:18:33 GMT

    [ https://issues.apache.org/jira/browse/PIG-2317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13239595#comment-13239595

Jonathan Coveney commented on PIG-2317:
---------------------------------------

Russell: each pass (excluding a couple of the _plus patches), is the full patch. So you just
download the patch, put it in the base directory of a clean-esque pig folder, and do "patch
-p0 < PIG-2317_13.patch"

At that point, you can register a script as:

register 'udf2.rb' using jruby as myfuncs;

And so on. Check out: test/e2e/pig/udfs/ruby/ for two scripts used in the e2e tests.

Let me rebase a version for a clean apply against 0.10... I wasn't sure if we were going to
have this be in the RC so I've been working against trunk. It should apply fine against 0.10,
just a little offset stuff, so I'll do that in a little and attach it...but let me know if
what I said above doesn't work or make sense once I do.

> It should be possible to write UDFs in Ruby. These UDFs will be registered in the same
way as python and javascript UDFs.
