An Eclipse plugin for Pig. In addition to standard syntax highlighting it supports graphical construction of Pig Latin scripts (box and arrow) as well as showing the user the output schema of each line in a Pig Latin script and example output of his or her script. Pig can be run directly from !PigPen in either local or Map-Reduce mode.

A Python wrapper that helps users manage their Pig processes. It can manage many similar Pig Latin scripts, including running common root scripts and caching the results to be used in generation of the final output scripts. Pig can be run directly from !PigPy, allowing users to inspect results of the Pig job and take further actions.
