Revolute: Scala-based Query Language for Hadoop
Revolute aims to provide a rich SQL-like querying language (embedded DSL) inspired by Apache Hive and Scala Query.
The main benefit over Apache Hive is the increased expressivity -- with Scala's powerful abstraction and composition facilities at your disposal.
Revolute is essentialy "thin layer" on top of Cascading, which provides the muscle and a simplified working model for big data processing, including (but not limited to) deployment on top of Apache Hadoop, an engaged open-source community, and an wide ecosystem of extensions (sinks, taps, serializers, etc).
Revolute is a work-in-progress. It is underdoing heavy development and is not considered stable at the moment.
You need Apache Buildr 1.4.x or higher.
# compile, test and package .jars buildr package

And in the documentation.
