Adding access to external S3 buckets for Cloudera Data Warehouse clusters on AWS
You can add and query data in S3 buckets you add to Cloudera Data Warehouse (CDW) service clusters running on AWS environments.
Access to these two buckets is controlled by 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.
