    Description

      The hadoop-site.xml generated by hadoop-ec2-init-remote.sh makes a number of parameters final, per below it looks like some of these might be reasonably be over-ridden (eg you can override mapred.child.java.opts but not mapred.child.ulimit).

      Would be great if hadoop-site.xml was pulled out into a separate file so users could see the template and easily update it with specific values they want to set.
