Attaching a managed policy ARN

For security reasons, if you do not want to provide PutRolePolicy permission in your cross account role, which would be used later to add an inline policy to the Node instance role, you must create a managed policy. Failure to do so results in an authorization error. You learn how to create the managed policy in a few steps.

If you are using the restricted policy with managed policy ARN, you need to add the permission to the cross account role from this Github link.
  1. Follow instructions in steps 1-4 to activate your environment in Cloudera Data Warehouse, as described in the "Activating an AWS environment" above.
  2. Select Attach Managed policy ARN to Node Role, and pass the ARN.
    For example:
    When you remove the PutRolePolicy permission, which is one of the standard permissions needed, from your cross account role, the reduced permissions mode UI appears.
    For example:
    For more information about reduced permissions mode, see the topic below.
  3. In Environmental Activations, optionally do not select Reduced Permissions mode.
  4. Click Activate.
    The noderole-inline-policy.json is attached to the Node Instance role instead of a inline policy requiring the PutRolePolicy permission in your cross account role.
  5. Make the following changes to the noderole-inline-policy.json file in your cross account role:
    • ${DATALAKE_BUCKET} - Replace this with the name of your S3 bucket. For example my-bucket.
    • ${STORAGE_LOCATION_BASE} - Replace this with the path to your Data Lake directory in the S3 bucket specified as ${DATALAKE_BUCKET}{}/SOME_PATH. For example my-bucket/my-dl.
    • ${LOGS_BUCKET} - Replace this with the name of your S3 bucket for logs. For example my-bucket. ${LOGS_LOCATION_BASE} - Replace this with the path to your S3 location for logs. For example my-bucket/my-dl.
    • ${BACKUP_LOCATION_BASE} - Replace this with the path to your S3 location for backups. This location is used for both FreeIPA and Data Lake backups. For example my-bucket/my-dl.
    • ${BACKUP_BUCKET} - Replace this with the name of your S3 bucket for backup. For example my-bucket.
