Cluster Naming and Version Selection

Follow the below guidelines for cluster naming and version selection.

Name Your Cluster

Steps

1. In Name your cluster, type a name for the cluster you want to create. Use no white spaces or special characters in the name.

Note If you plan to Kerberize the cluster, consider limiting the cluster name (to 12 characters or less), to accommodate the fact that Kerberos principals will be appended to the cluster name string and that some identity providers impose a limit on the total principal name length.

2. Choose Next.

Select Version

In this Step, you will select the software version and method of delivery for your cluster. Using a Public Repository requires Internet connectivity. Using a Local Repository requires you have configured the software in a repository available in your network.

Choosing Stack

The available versions are shown in TABs. When you select a TAB, Ambari attempts to discover what specific version of that Stack is available. That list is shown in a DROPDOWN. For that specific version, the available Services are displayed, with their Versions shown in the TABLE.

Choosing Version

If Ambari has access to the Internet, the specific versions will be listed as options in the DROPDOWN. Once you select the version from the drop-down, the repository URLs will be displayed. In the repository URLs, you must include the username:password (credentials).

If you have a Version Definition File for a version that is not listed, you can click Add Version… and upload the VDF file. If you are uploading the VDF file, make sure to append the credentials to the base URL. If you are providing the VDF URL, you must include the username:password in the URL.

In addition, a Default Version Definition is also included in the list if you do not have Internet access or are not sure which specific version to install.

Note In case your Ambari Server has access to the Internet but has to go through an Internet Proxy Server, be sure to set up the Ambari Server for an Internet Proxy.

Choosing Repositories

Ambari gives you a choice to install the software from the Public Repositories (if you have Internet access) or Local Repositories. Regardless of your choice, you can edit the Base URL of the repositories. The available operating systems are displayed and you can add or remove operating systems from the list to fit your environment.

The UI displays repository Base URLs based on the Operating System Family (OS Family). Be sure to set the correct OS Family based on the Operating System you are running.

Advanced Options

There are advanced repository options available.

• Skip Repository Base URL validation (Advanced): When you click Next, Ambari will attempt to connect to the repository Base URLs and validate that you have entered a validate repository. If not, an error will be shown that you must correct before proceeding.
