Cluster Management - Big Data Made Easy: A Working Guide to the Complete Hadoop Toolset - page 235

I click the Continue button to move to the Select Repository page and choose the installation method,
packages, or parcels (advised). Here, I can also specify the version of CDH to install and any extra parcels, such as
Accumulo. Figure 8-11 shows this repository, with additional parcels like Accumulo and Sqoop to be chosen for
installation, if needed.

I choose to install CDH 5.1.2, as shown in Figure 8-11 . I had already installed CDH 4 in Chapter 2, so that
installing CDH5 with the cluster manager is a progression from that previous work.
I click Continue once more, and consider enabling Java encryption. In this example, I leave my installation as the
default option without encryption, simply by clicking Continue to move on.
At the next cluster installation page, which has the title “Provide SSH Login Credentials,” I enter my installation
login credentials. I choose to use the root user and enter the user's password. This time when I click Continue the
actual installation of the Cloudera agent and server modules begins. Banners indicate both the overall progress and
the individual progress per server. Figure 8-12 shows a successful installation. I click Continue again to move on to
installing the selected parcels.
