Prerequisites
To get started in Cloudera Data Warehouse (CDW), your data must conform to supported compression codecs, and you must obtain CDP resource roles to grant users access to an environment. Users can then get started on CDW tasks, such as activating the environment from CDW.
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
- 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 Virtual Warehouses.
- DWUser: This role enables users or groups to view and use CDW clusters (Virtual Warehouses) that are associated with specific environments.
A CDP PowerUser assigns these roles to users who require access to the Virtual Warehouses that are associated with specific environments. A default Database Catalog is associated with your environment. After granting these roles to users and groups, they then have Single Sign-On (SSO) access to the Virtual Warehouses.
