https://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/latest/CDH5-Installation-Guide/CDH5-Installation-Guide.html

provides instructions to upgrade from CDH4 to CDH5 (which bundles Hadoop 2.3.0). If you intention is to use CDH5 that should help you.

If your intention is to use Apache Hadoop 2.4.0, some of CDH documentation above may still be relevant.
