Cloudera(tm) Hadoop Integration Guide
To get Cloudera Hadoop running within your QuantaStor system the steps are basically the same as they would be with a standard Ubuntu Precise server. Essentially you'll need to login to your system using SSH or use the console then run these commands.
Step 1 - Add the Cloudera package server
Run this command to add the GPG key for Cloudera's packages.
curl -s http://archive.cloudera.com/cdh4/ubuntu/precise/amd64/cdh/archive.key | sudo apt-key add -
Next you'll need to tell QuantaStor where the Cloudera package servers are located by creating a sources file called /etc/apt/sources.list.d/cloudera.list with the following contents:
deb [arch=amd64] http://archive.cloudera.com/cdh4/ubuntu/precise/amd64/cdh precise-cdh4 contrib
deb-src http://archive.cloudera.com/cdh4/ubuntu/precise/amd64/cdh precise-cdh4 contrib
