The Hadoop Common Documentation describes the common utilities and libraries that support the other Hadoop subprojects.  
  </p>
  <p>
The Hadoop Common Documentation also includes the information you need to get started using Hadoop. 
Begin with the Hadoop <a href="single_node_setup.html">Single Node Setup</a> which shows you how to set up a single-node Hadoop installation. 
Then move on to the Hadoop <a href="cluster_setup.html">Cluster Setup</a> to learn how to set up a multi-node Hadoop installation. 
</p>
 <p>
   Cluster environments commonly work in tandem with MapReduce applications and distributed file systems. 
   For information about MapReduce see the 
 <a href="http://hadoop.apache.org/mapreduce/docs/current/index.html">MapReduce Documentation</a>.
   For information about the Hadoop Distributed File System (HDFS) see the 
 <a href="http://hadoop.apache.org/hdfs/docs/current/index.html">HDFS Documentation</a>.
  </p>

If you have more questions, you can ask on the <a href="ext:lists">Hadoop Common Mailing Lists</a> or browse the <a href="ext:archive">Mailing List Archives</a>.
