Cloudera Development Kit

Cloudera Development Kit

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.

Eric Sammer recorded a webinar in which he talks about the goals of the CDK.

This project is organized into modules. Modules may be independent or have dependencies on other modules within the CDK. When possible, dependencies on external projects are minimized.

Modules

The following modules currently exist.

CDK Data

The data module provides logical abstractions on top of storage subsystems (e.g. HDFS) that let users think and operate in terms of records, datasets, and dataset repositories. If you're looking to read or write records directly to/from a storage system, the data module is for you.

CDK Maven Plugin

The CDK Maven Plugin provides Maven goals for packaging, deploying, and running distributed applications.

CDK Morphlines

The Morphlines module reduces the time and skills necessary to build and change Hadoop ETL stream processing applications that extract, transform and load data into Apache Solr, Enterprise Data Warehouses, HDFS, HBase or Analytic Online Dashboards.

CDK Tools

The tools module provides command-line tools and APIs for performing common tasks with the CDK.

Examples

Example code demonstrating how to use the CDK can be found in the separate GitHub repository at https://github.com/cloudera/cdk-examples
