Cascading
Cascading is a feature rich API for defining and executing complex, scale-free, and fault tolerant data processing workflows on a Hadoop cluster.
The processing API lets the developer quickly assemble complex distributed processes without having to “think” in MapReduce. And to efficiently schedule them based on their dependencies and other available meta-data. Obviously simple data processing applications are supported as well, as complex jobs tend to start simple.
Cascading is Open Source and dual licensed under the GPL and OEM/Commercial Licenses. OEM/Commercial Licenses and Developer Support can be obtained through Concurrent, Inc.
