Kyungho Jeon commented on PIG-2597:
-----------------------------------
This is my initial draft:
https://github.com/kyunghoj/GSoC2014
I am not sure how much details should be in design section. Also, I realized
that other components based on JavaCC (e.g., Parameter substitution) might be
bigger beasts. Should those component be included in this project?
> Move grunt from javacc to ANTRL

> Currently, the parser for queries is in ANTLR, but Grunt is still javacc. The
> parser is very difficult to work with, and next to impossible to understand
> or modify. ANTLR provides a much cleaner, more standard way to generate
> parsers/lexers/ASTs/etc, and moving from javacc to Grunt would be huge as we
> continue to add features to Pig.
> This is a candidate project for Google summer of code 2014. More information
