Adding a Service
After using the Management Console to set up a cluster, you can add additional services.
- The default configuration of new services may not match with the public cloud environment, and the new service may not start up successfully. To find the correct configuration parameters for CDP Public Cloud, check the service configuration parameters in the Cloudera-provided cluster templates.
- Using the Cloudera Manager Add Service feature to manually add services can be error-prone and non-reproducible. Cloudera suggests using a cluster template to configure services, so that the configuration parameters for each service are captured, making it simple to re-create the cluster with all services.
- You can use Cloudera-provided cluster templates, or create custom cluster templates by starting with a Cloudera-provided cluster template as a base.
When adding a service in CDP Public Cloud, you use the Host Templates created during set up of the cluster to add role groups for each of the roles in a service. You cannot add a role directly to a host. After adding the appropriate role group to the Host Template, you can scale up the cluster by applying the Host Template to the host. You can then re-apply the Host Template to all hosts, or you can scale up the cluster by applying a Host Template to the new hosts.
Each role should be assigned to a Host Template that is configured for master, worker, or gateway roles. Templates for master roles usually assign the role to a single host. Templates for worker or gateway hosts can assign roles to multiple hosts.
