Description
The wiki page that describes running Hadoop on Amazon EC2 (http://wiki.apache.org/lucene-hadoop/AmazonEC2) includes a large number of instructions for manually building images and launching instances using EC2 tools. We now have a set of automated scripts for doing these tasks (see HADOOP-884, HADOOP-952), so I propose removing the manual instructions (also, they are likely to become inaccurate over time, and may make the idea of using Hadoop on EC2 daunting to new users).
As a part of this I will keep the parts of the documentation that explain the concepts, and document what the scripts do in more detail.
