Select Services

The Select Services page allows you to select the services you want to install and configure.

important

In case you deploy a scratch cluster that has not yet been kerberized, you cannot choose any service that requires Kerberos as a pre-requisite, including Ranger, RangerKMS, Atlas, and Knox.

Each of these services will carry such note near it (see example for Ranger):

Choosing either of these services to be installed without having a Kerberos-based cluster will lead to a non-functioning cluster. It is advised to install these services separately only after enabling Kerberos on the cluster. For more information, see Set up a KDC.

After selecting the services you want to add, click Continue. The Assign Roles page displays.

Note that if you did not add Kerberos to the cluster at the beginning of the Wizard (i.e. setting Cloudera Manager as Key Distribution Center), you will need to choose only Customer Services option and pick the non-kerberos services you want to deploy, and only post enabling Kerberos, you will repeat the Wizard and complete the Kerberos based services.

Select one of the following options:

Regular (Base) Clusters

Data Engineering: Process develop, and serve predictive models.; Services included: HDFS, YARN, YARN Queue Manager, Ranger, Atlas, Hive, Hive on Tez, Spark, Oozie, and Hue
Data Mart: Browse, query, and explore your data in an interactive way.; Services included: HDFS, Ranger, Atlas, Hive, and Hue
Operational Database: Real-time insights for modern data-driven business.; Services included: HDFS, Ranger, Atlas, and HBase
Custom Services: Choose your own services. Services required by chosen services will automatically be included.
note

In most cases, you will choose Custom Services and will pick the services that were purchased by the customer. Remember that if this is a scratch cluster installation and KDC/TLS were not installed, any service marked with a red note stating This service requires Kerberos can be installed now.

After picking the services you would like to deploy, for each service you will be asked to choose the nodes on which the service will be deployed. Assign the service as instructed by Cloudera according to the Cloudera pre-defined role distribution design table.
note

Though the Wizard installs the services chosen, some functions that are required for these services are not installed during the Wizard's initial installation due to dependencies and will need to be added later manually, such as service GateWays for HBASE, HDFS, Solr, and Yarn. To add them manually later, once the cluster is up, simply go to the service instances page, choose to add a role instance, pick the Gateway instance, and assign it according to the Cloudera pre-defined role distribution design table to the correct nodes.
