Watchtower - Instant feedback development tool for Pig

In their words “Light Table” for Pig:

Watchtower is a daemon that sits in the background, continuously flowing a sample of your data through your script while your work. It captures what your data looks like, and shows how it mutates at each step, directly inline with your script.

Sweeet! It will not guarantee that your Pig script is correct or catch all the errors, but having immediate feedback when developing for an environment that consumes resources is priceless.

And no, unit testing Pig scripts is not the same.
