CDH 4.1.2

Cloudera’s 100% Open Source Hadoop Platform

CDH is Cloudera's open source software distribution and consists of Apache Hadoop and additional key open source projects to ensure you get the most out of Hadoop and your data.

It is the only Hadoop solution to offer unified querying options (including batch processing, interactive SQL, text search, and machine learning) and necessary enterprise security features (such as role-based access controls).

Please note: CDH requires manual installation from the command line.
