Overview

The Hadoop Common Documentation describes the common utilities and libraries that support the other Hadoop subprojects.

The Hadoop Common Documentation also includes the information you need to get started using Hadoop. Begin with the Hadoop Single Node Setup which shows you how to set up a single-node Hadoop installation. Then move on to the Hadoop Cluster Setup to learn how to set up a multi-node Hadoop installation.

Cluster environments commonly work in tandem with MapReduce applications and distributed file systems. For information about MapReduce see the MapReduce Documentation. For information about the Hadoop Distributed File System (HDFS) see the HDFS Documentation.

If you have more questions, you can ask on the Hadoop Common Mailing Lists or browse the Mailing List Archives.
