4. Install Options

In order to build up the cluster, the install wizard needs to know general information about how you want to set up your cluster. You need to supply the FQDN of each of your hosts. The wizard also needs to access the private key file you created in Set Up Password-less SSH It uses these to locate all the hosts in the system and to access and interact with them securely.

Use the Target Hosts text box to enter your list of host names, one per line. You can use ranges inside brackets to indicate larger sets of hosts. For example, for host01.domain through host10.domain use host[01-10].domain

	Note
	If you are deploying on EC2, use the internal Private DNS hostnames.

If you want to let Ambari automatically install the Ambari Agent on all your hosts using SSH, select Provide your SSH Private Key and either use the Choose File button in the Host Registration Information section to find the private key file that matches the public key you installed earlier on all your hosts or cut and paste the key into the text box manually.

	Note
	If you are using IE 9, the Choose File button may not appear. Use the text box to cut and paste your private key manually.

Fill in the username for the SSH key you have selected. If you do not wish to use root, you must provide the username for an account that can execute sudo without entering a password.

If you do not wish to have Ambari automatically install the Ambari Agents, select Perform manual registration. See Appendix: Installing Ambari Agents Manually for more information.
Advanced Options
- If you want to use a local software repository (for example, if your installation does not have access to the Internet), check Use a local software repository. For more information on using a local repository see Optional: Configure the Local Repositories
- If you want to use an existing JDK rather than installing a fresh copy in the default location, check Path to 64-bit JDK JAVA_HOME and put the path in the text box. Note: this path must be valid on all the hosts in your cluster.
Click the Register and Confirm button to continue.
