Hi Jacob,

Thanks very much for helping me out. I haven't heard of Wukong before.
I am a bit concerned though by adding Ruby into my tool stack as well as
Pig. It seems like a step too far.
Presumably I have to distribute Ruby and Wukong across all my job nodes in
the same way as if I were writing perl or C++ streaming programs.

With STREAMing - the script is launched once per file, right, not once per
record?
