Thanks Jeff! The thing is that I wanted to see the exact moment when pig was converting the query into the operators, but as you said, it would be better if I see other parts of the code. I will have to reproduce mentally how gruntParser uses PigScriptParser.parse :) Do you know when this technology switch will happen? I read it was going to be in 0.9, but that is july or august of the next year? Will there be code restructuring due to this? Thanks in advance.
