Installing Cloudera Hadoop 0.20 and Mahout on Ubuntu 11

Notes for installing Cloudera Hadoop 0.20 and Mahout on Ubuntu 11.10
April 2012

UPDATE SEPT 2014 - ok this is very old now.  A better way is to just use the Cloudera CDH installer!
# wget http://archive.cloudera.com/cm5/installer/latest/cloudera-manager-installer.bin
# chmod u+x cloudera-manager-installer.bin
# sudo ./cloudera-manager-installer.bin
Then follow the local installer steps before navigating to the web installer when prompted.
