For point 3, a brief description is ...
Cloudera is a software that comes with in build Apache Hadoop (We call it CDH ie Cloudera Distribution of Hadoop) and in built OS called Ubantu. So here we dont need to configure anything. Just take the VM,map to Cloudera software that s it you are ready to go.
Now say you want to have Ubantu(OS) install in a machine separately in ur Virtual machine. Than you need to take the tar of Hadoop than untar it map it etc..In this case u need to have SSH certificates etc...so thats the document that you highlighted in point 3 mentioned.
Hope this helps.
