Profiles¶

The Profiles tab allow you to define individual cluster sizes and configurations. Admins can then give different users access to the different clusters by specifying a specific profile when launching a new cluster.

Enterprise Steam comes with four profiles:

• default-h2o: This is enabled by default.
• default-sparkling-internal: This is disabled by default. Configure Spark settings to enable this profile. (See the Spark section for more information.)
• default-sparkling-external: This is disabled by default. Configure Spark settings to enable this profile. (See the Spark section for more information.)
• default-dai: This is disabled by default. Configure Driverless AI settings to enable this profile. (See the Driverless AI section for more information.)

Note: The minimum Sparkling Water versions are 2.1.41, 2.2.27, 2.3.16, 2.4.*

1. On the Configurations page, click the Profiles tab. This page shows a list of available profiles.
2. In the Create New Profile section of this page, enter a name for the new profile and select an available type (H2O, Sparkling Water - Internal Backend, Sparkling Water - External Backend). Click Create when you are ready. This opens the Creating Profiles form. Note that this form varies depending on the Type.
