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.
