3. Adding a Service

The Ambari install wizard installs all available Hadoop services by default. You may choose to deploy only some services initially, then add other services at later times. For example, many customers deploy only core Hadoop services initially. Add Service supports deploying additional services without interrupting operations in your Hadoop cluster. When you have deployed all available services, Add Service displays disabled.

For example, if you are using HDP 2.2 Stack and did not install Falcon or Storm, you can use the Add Service capability to add those services to your cluster.

To add a service, select Actions > Add Service, then complete the following procedure using the Add Service Wizard.
