Tools that help run Pig workflows

'hamake' utility allows you to automate incremental processing of datasets stored on HDFS using Hadoop tasks written in Java or using PigLatin scripts.

Mortar Data

http://mortardata.com/platform

Mortar Data's platform-as-a-service hosts and executes jobs written in the Mortar framework or in the platform's built-in web interface. Powered in part by Amazon's Elastic MapReduce, Mortar's PaaS provides full code history (backed by GitHub), automatic job scheduling (or running them via API), and emails you about job successes/failures. It also gives you instant feedback while you're coding and executing, so you can quickly find and fix errors and bottlenecks in your code.

Mortar Framework

http://mortar-framework.org

Mortar is an open source framework for building, organizing, testing, and deploying projects using Pig. Inspired by the project structure of web frameworks like Rails, Mortar makes Pig much easier to work with by providing great utilities, cutting out boilerplate work, and by providing a standard place for your control scripts, Pig code, UDFs, tests, and libraries.

Piglet

http://github.com/iconara/piglet

Piglet is a DSL for writing Pig Latin scripts in Ruby. Piglet aims to look like Pig Latin while allowing for things like loops and control of flow that are missing from Pig.

PigPy

http://code.google.com/p/pigpy/

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.
