TSB 2025-858: Cloudera Data Warehouse provisioning failures due to storage policies

Learn more about the details communicated in TSB-858.

Summary
Restrictive Azure storage policies may cause Hive and Impala Warehouse provisioning and upgrade to fail on Azure cloud.
Cloudera Data Warehouse version 1.10.1 introduced a new persistent volume for Hue to store SQL AI sentence transformer models. This storage is required for the new Hue SQL AI Assistant feature, where customers can move the already downloaded/scanned sentence transformer models to the /etc/hue/models directory.
For this purpose, Cloudera Data Warehouse attempts to provision Azure storage, using storage accounts with public access enabled by default for storing the models.
Customers may have stricter security policies that:
  • Deny the creation of storage accounts with public access

  • Restrict Cloudera's ability to create new storage accounts in their Azure subscription.

In such cases, if a customer’s Azure policy blocks the creation of public storage accounts, provisioning of the persistent volume for Hue and the Hive and Impala Virtual Warehouse provisioning fails due to the Azure policy violation.
