Cloudera’s Distribution Including Apache Hadoop (hereafter CDH) is an integrated Apache Hadoop-based stack containing all the components needed for production use, tested and packaged to work together. Cloudera makes the distribution available in a number of different formats: Linux packages, virtual machine images, tarballs, and scripts for running CDH in the cloud.
