What's new in Cloudera Data Warehouse on cloud

Migration from NGINX to Istio in Cloudera Data Warehouse on cloud

Starting with the 1.12.4 release, Cloudera Data Warehouse no longer uses the NGINX Ingress Controller for new environments. Instead, Ingress traffic is managed using the Kubernetes Gateway API with an Istio gateway controller.

For new environments created on 1.12.4 or higher, the Ingress layer is managed by Istio, and workloads from this release utilize Gateway resources instead of Ingress resources. Consequently, workloads (Hive, Impala, or Trino) with 2025.0.21.0 or earlier, which were designed to work only with Ingress resources, cannot be deployed in 1.12.4 or higher environments.

For existing environments created before 1.12.4, the NGINX Ingress Controller continues to manage ingress traffic. These environments remain compatible with the latest supported Cloudera Data Warehouse workloads that work with NGINX. There is no automatic migration of existing environments to Istio.

This change ensures long-term support and security, as the Ingress-NGINX project is being retired with only best-effort maintenance available until March 2026.

Deprecation of Unified Analytics for Impala: Starting with this release, Cloudera Data Warehouse on cloud restricts the management of legacy Impala Virtual Warehouses that use Unified Analytics. In this release, rebuilding existing Impala Virtual Warehouses enabled with Unified Analytics is disabled. This follows the earlier release where creating new Unified Analytics-enabled Virtual Warehouses was deactivated.
To provide a migration path, you can upgrade your existing Unified Analytics-enabled Impala Virtual Warehouses to the latest version using the CDP CLI. The upgrade process disables Unified Analytics and removes its related configurations while keeping all other settings. For more information, see Migrating stored Hive queries after Unified Analytics removal .

New activation pages for AWS and Azure environments: The Activate Environment page in Cloudera Data Warehouse on cloud is redesigned for AWS and Azure environment. The legacy pop-up modal screens are replaced with dedicated, full-page guided layouts. This update streamlines the activation flow into clear, intuitive steps that align with the latest Cloudera Data Warehouse navigation patterns and complete setup with minimal clicks.
