The steps may vary for your specific platform, but the general cases are: • Download the ISO for the OS you are going to install. o For Ubuntu 14.04, please see the Ubuntu website. • For the IPMI configuration supported by your server, connect to the virtual console of your server. • Attach the ISO that you downloaded for your OS as a virtual device for your server. • Boot the ISO. • Set the appropriate data as the install runs: o Language o "Install Ubuntu Server" o Manual Network Configuration Refer to the static IP address you selected previously for this node. o Hostname o Username and password o Do not encrypt home directories o Time zone o Partition Your file system should be independent from your HDFS file system. Partitioning depends on the number and size of drives that you have in your systems. o Enable Openssh server o Install Grub • Once the install is complete, ensure you disconnect the ISO image so that the system will boot into your new OS. • Repeat the above steps for each system in your cluster. As your installs complete, verify you can reach each of them by connecting via SSH to their IP addresses and logging in with the user account you created. 9. Ensure Common Services Are Set Up If you are leveraging DNS, DHCP or other dynamic common services in your cluster, you should configure them before proceeding. • For setting up DNS, please see the ISC-Bind9 guides • For setting up DHCP, please see the ISC-DHCP guides • For setting up Dynamic DNS via DHCP, please see the ISC Dynamic DNS setup guide 10.

Please follow the steps in the Hadoop Manual Install Guide published by Hortonworks to bring the remaining software components of your big data cluster up. Once you have completed your Hadoop cluster setup, you can run various tests to ensure the overall operation of the system is functional. Example test cases are: • TeraGen • TeraSort • TeraValidate • Calculate pi
