Re: need help about pig script on this case
In pure Pig, you wouldn't do something like this. However, PIg supports
control flow in Python (I really should get on making the JRuby wrapper,
but I digress). You can find docs for this on the pig website. Basically
the control flow is in Python, and you launch jobs from there.
