"The Cloudera Development Kit, or CDK for short, is a set of libraries, tools, examples, and documentation focused on making it easier to build systems on top of the Hadoop ecosystem.
The goals of the CDK are:
Codify expert patterns and practices for building data-oriented systems and applications.
Let developers focus on business logic, not plumbing or infrastructure.
Provide smart defaults for platform choices.
Support piecemeal adoption via loosely-coupled modules."
