-Re: Ruby 1.9 and jRuby 1.7

I implemented most of the jruby stuff. Glad to hear you're trying it out!
Please let us know what your experience is like.
I definitely had plans to upgrade to jruby 1.7, and am not sure why I never
Ahh, ok, it's part of this patch...which still isn't committed...you should
bump it :)
I definitely think we should upgrade, and 1.9 should be the default.
That said, if you
check src/org/apache/pig/scripting/jruby/JrubyScriptEngine.java , the ruby
engine it attempts to set up is 1.9 BUT in 1.6.7 this can be buggy. To be
absolutely sure you need to set an environment variable (I think that's
documented in the JIRA).
Mainly we should just apply that patch :)
