Prerequisites

To get started in Cloudera Data Warehouse, your data must conform to supported compression codecs, and you must obtain CDP resource roles to grant users access to a public cloud environment. Users can then get started on CDW tasks, such as activating the environment from Cloudera Data Warehouse (CDW) service.

Unsupported compression

CDW does not support LZO compression due to licensing of the LZO library. You cannot query tables having LZO compression in Virtual Warehouses, which use CDW Impala or Hive LLAP engines.

CDP resource roles

Required role: PowerUser

The following CDP resource roles are associated with the CDW service. A CDP PowerUser must assign these roles to users who require access to the Database Catalogs and Virtual Warehouses that are associated with specific environments. After granting these roles to users and groups, they then have Single Sign-On (SSO) access to the Data Catalogs and Virtual Warehouses that are associated with the environment.
  • DWAdmin This role enables users or groups to grant a CDP user or group the ability to activate, terminate, launch, stop, or update services in Database Catalogs and Virtual Warehouses.
  • DWUser This role enables users or groups to view and use CDW clusters (Virtual Warehouses) that are associated with specific environments.
