In this section, we will learn how to set up a brand new Hadoop cluster from scratch using Ambari. In order to do this, we are going to need four servers – one server for running the Ambari server and three other nodes for running the Hadoop components.

Server configurations
The following table displays the configurations of the servers we are using as part of this exercise:
Server Type |
Name |
CPU |
RAM |
DISK |
Ambari Server node |
master |
