I take the time to go through the configuration list to be sure that I am happy both with what is going to be
installed and with the servers on which everything will be installed.
In the Review Configuration window, I click Deploy to move to the next page. The next window gives me a list
of components that will be installed. I select Next to start the installation, which takes around 30 minutes. Figure 8-4
shows the results of the successful installation.

visual overview of the Hadoop cluster, showing the services available and the state of resources in the cluster.
Figure 8-5 , for example, displays the dashboard's Metrics tab.
