This release of the Cloudera Data Warehouse (CDW) service on CDP Public Cloud introduces the following new features and behavioral changes.

Reduced permissions mode for AWS environments

This feature enables you to activate an AWS environment for CDW with fewer than half of the standard required IAM permissions on your AWS cross-account IAM role. This is useful if your InfoSec policies do not permit you to use the standard set of required permissions.

When activating an AWS environment in CDW, if the system detects that your account does not have the standard set of required IAM permissions, it invokes this feature automatically. Then you must manually create the cloud resources in your AWS account and tag them appropriately instead of having CDW do this for you. To assist you, CDW pre-populates the required CloudFormation template for you within the AWS Console, but you must perform the manual steps to create the stack. When you are finished using the stack, you must manually delete it in the AWS Console. For more information about this feature, see Reduced permissions mode for AWS environments.
