Sapna,

As explained by Karan in the last class, CDH5 is a complete package with all the required hadoop stuffs pre-configured. Since its been set up in a VM, it acts as a single node, but will be in pseudo distributed mode. i.e. even though it will show the different node details, all will have the same ip address and details.

You can't create anything with CDH5, as its an image created by cloudera.

If you want to manually install everything by yourself, then you need to have all the required stuffs downloaded and install it all by yourself and configure it out. To have it in multi node, you need to have multiple PCs to do it. 

Since this course is for the developer training, pseudo distributed mode is more than enough. Multinode installations are being done by the corporates and not for training purpose. Or else you need to get access to any training site which offers multinode set up for learning purpose.

Hope its clear.
