  The Hadoop MapReduce Documentation provides the information you need to get started writing MapReduce applications. 
  Begin with the <a href="mapred_tutorial.html">MapReduce Tutorial</a> which shows you how to write MapReduce applications using Java. 
  To write MapReduce applications in languages other than Java see <a href="streaming.html">Hadoop Streaming</a>, a utility that allows you to create
  and run jobs with any executable as the mapper or reducer.
  </p>
  
  <p>
   MapReduce works in tandem with a cluster environment and a distributed file system. 
   For information about Hadoop clusters (single or multi node) see the 
 <a href="http://hadoop.apache.org/common/docs/current/index.html">Hadoop Common 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>.

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