Learn about the known issues in Cloudera Data Warehouse service in AWS environments, the impact or changes to the functionality, and workarounds.

DWX-6121 and DWX-5666: Instance tags are not propogated to Kubernetes ELB and EBS volumes
Problem: CDP applies custom tags during the creation of resources but the instance tags are not propagated to Kubernetes External Load Balancer (ELB) and Elastic Block Storage (EBS) volumes within the AWS environments.
DWX-6970: Tags do not get applied in existing CDW environments
Problem: You may see the following error while trying to apply tags to Virtual Warehouses in an existing CDW environment: An error occurred (UnauthorizedOperation) when calling the CreateTags operation: You are not authorized to perform this operation and Compute node tagging was unsuccessful. This happens because the ec2:CreateTags privilege is missing from your AWS cluster-autoscaler inline policy for the NodeInstanceRole role.
Workaround: Add the ec2:CreateTags privilege to the cluster-autoscaler inline policy as follows:
  1. Log into the AWS IAM console at https://console.aws.amazon.com/iam/.
  2. In the navigation panel, choose Roles.
  3. Search the list of roles for NodeInstanceRole.
  4. Click Permissions.
  5. Select cluster-autoscaler and click Edit policy.
  6. Add the ec2:CreateTags line in the Actions section after the ec2:DescribeLaunchTemplateVersions line as shown:
    "Version": "2012-10-17",
        "Statement": [
            {
                "Action": [
                    "autoscaling:DescribeAutoScalingGroups",
                    "autoscaling:DescribeAutoScalingInstances",
                    "autoscaling:DescribeTags",
                    "autoscaling:DescribeLaunchConfigurations",
                    "autoscaling:SetDesiredCapacity",
                    "autoscaling:TerminateInstanceInAutoScalingGroup",
                    "ec2:DescribeLaunchTemplateVersions",
                    "ec2:CreateTags"
                ],
