Installing and configuring hadoop single node on a red hat 6

Prerequisite:
Make sure that Java 6 is already installed and then set the environment variable to ensure that hadoop finds it.

$  export JAVA_HOME=/usr/

Note: My path to java may be different then yours. For example if your java installation is located at '/usr/bin/java' then this will work.

Download the rpm that works on your platform at the following url:
http://rpm.pbone.net/index.php3/stat/4/idpl/21508839/dir/other/com/hadoop-1.1.2-1.i386.rpm.html


you can double click it and install it:

Then run the following command:


$ sudo /usr/sbin/hadoop-setup-single-node.sh

$ sudo /usr/sbin/hadoop-create-user.sh -u $USER


DONE!!!

You have now installed hadoop. Enjoy....
