| 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>. |
