title: For a single CDH (Hadoop) cluster installation, which host should I use?
body: <p>I started with a Windows 7 computer, and set up an Ubuntu Linux virtual machine <code>which I run using VirtualBox</code>. <code>The Cloudera Manager Free Edition version 4</code> has been executed, and I have been following the prompts on <code>localhost:7180</code>. </p>
  
  <p>I am now stuck when the prompt asks me to "Specify hosts for your CDH cluster installation." Can I install all of the Hadoop components, as well as run them, in the linux virtual machine alone?</p>
  
  <p>Please help point me in the right direction in which host I should specify.</p>
