How to install Hadoop on Ubuntu

Question

I'm trying to follow this tutorial http://mysolvedproblem.blogspot.com/2012/05/installing-hadoop-on-ubuntu-linux-on.html and instead of hadoop-0.20.2.tar.gz I downloaded the latest version which is hadoop-0.23.6.tar.gz. And I stuck on one step, where I have to change hadoop-env.sh file. The thing is I couldn't find /conf/ folder at all. and also I couldn't find this file also. Can I continue without making changes on this file?

For version 2.2.0 it's located at:
