After configuring automatic install of bare metal (No OS pre-installed) nodes, deploying a Hadoop cluster will be a matter of clicks. The setup uses:</p> <ul> <li><strong>PXE boot</strong> (for automatic OS install)</li> <li><strong>TFTP server</strong> (for PXE network install image)</li> <li><strong>Apache server</strong> (to serve the kickstart file for unattended install)</li> <li><strong>DHCP server</strong> (for assigning IP addresses for the nodes)</li> <li><strong>DNS server</strong> (for internal domain name resolution)</li> <li><strong>Puppet-master</strong> (for automatic configuration management of all hosts in the network, Ambari install included in Puppet manifests)</li> <li><strong>Ambari-master and agents</strong> (for managing Hadoop ecosystem deployment)</li> </ul> <p>The setup assumes that the nodes are on the <em>192.168.0.0/255.255.255.0</em> network, the master is on <em>192.168.0.1</em> and its hostname is <em>bigdata1.hdp</em> The domain for the network server by the configuration is <em>hdp</em> and the clients are named as <em>bigdata[1-254].hdp</em> <a href="https://dataprd.com/files/2014/08/provision.zip" title="Hadoop Kickstart install"> Download all files here (configuration files, PXEBoot Linux image, Kickstart file and custom script for adding a node on the master).</a></p>
