Hadoop 1.0.3 2. Ubuntu 10.04  or above (Tested on 11.04, 11.10 and 12.04 32bit platform) Here is the details on how to install Hadoop using the script Please Readme - hadoop script to setup Single Node Cluster - For Hadoop 1.0.3 Only. - Tested on Ubuntu 11.10, 12.04 - Fresh Install. - Scripts assumes nothing is installed for Hadoop and installs Required Components for Hadoop to run. - This Script was c
