Cloudera Data Hub Overview

Core concepts

The following concepts are key to understanding the Cloudera Data Hub:

Workload clusters
All Cloudera Data Hub clusters are workload clusters. These clusters are created for running specific workloads such as data engineering or data analytics.
Cluster definitions
Cloudera Data Hub provides a set of default cluster definitions for prescriptive use cases and allows you to create your own custom cluster definitions.
Cluster templates
Cloudera Data Hub uses cluster templates for defining cluster topology: defining host groups and components installed on each host group.
Recipes
A recipe is a script that runs on all nodes of a selected host group at a specific time. You can use recipes to create and run scripts that perform specific tasks on your Cloudera Data Hub cluster nodes.
Custom properties
Custom properties are configuration properties that can be set on a Cloudera Runtime cluster, but Cloudera Data Hub allows you to conveniently set these during cluster creation.
Image catalogs
Cloudera Data Hub provides a set of default, prewarmed images. You can also customize the default images.
