Accessing S3 buckets in a managed policy environment

You can add and query data in S3 external buckets you add to Cloudera Data Warehouse (CDW) service clusters running on AWS environments.

This topic and the following subtopics are applicable if you are using managed policy ARN feature. If you are using RAZ enabled DW, see "Accessing buckets in a RAZ environment".

If you are not using a RAZ-enabled CDW, access to S3 buckets is controlled by the managed policy attached to the AWS instance profiles. To access S3 buckets you add to your CDW service cluster, you must edit the instance profile to add read/write permissions to the additional buckets as described in the following subtopics.
