Support for Pig
Pig is an open source, Apache library that runs on top of Hadoop. The library takes SQL-like commands in a language called Pig Latin and converts those commands into a MapReduce graph, which is executed on data in an Amazon EC2 cluster. So now, in addition to running MapReduce jobs using a JAR or stream, you can use Pig in programmatic or interactive modes.
