-------------------------------------
Initial test works:
---
register 'test.rb' using jruby as myfuncs;
A = load 'test/data/pigunit/top_queries_input_data.txt';
B = foreach A generate myfuncs.concat($0, $1);
---
require 'rubygems'
require 'pigudf'
require 'mail'
class Myudfs < PigUdf
def concat *input
input.inject(:+)
end
end
> SHIP and use JRuby gems in JRuby UDFs
