Cascading is a project providing a programming API for defining and executing fault tolerant data processing workflows on a Hadoop cluster. Cascading is a thin, open source Java library that sits on top of the Hadoop MapReduce layer. Cascading provides a query processing API that allows programmers to operate at a higher level than MapReduce, and to more quickly assemble complex distributed processes, and schedule them based on dependencies.

Cascading is an application framework for Java developers to quickly and easily develop robust Data Analytics and Data Management applications on Apache Hadoop
