General known issues on public clouds
Learn about the general known issues in Cloudera Data Warehouse (CDW) service on public clouds, the impact or changes to the functionality, and the workaround.
- DWX-5841: Virtual Warehouse endpoints are now restricted to TLS 1.2
- Problem: TLS 1.0 and 1.1 are no longer considered secure, so now Virtual Warehouse
endpoints must be secured with TLS 1.2 or later, and then the environment that the Virtual
Warehouse uses must be reactivated in CDW. This includes both Hive and Impala Virtual
Warehouses. To reactivate the environment in the CDW UI:
- Deactivate the environment. See Deactivating AWS environments or Deactivating Azure environments.
- Activate the environment. See Activating AWS environments or Activating Azure environments
- DWX-5742: Upgrading multiple Hive and Impala Virtual Warehouses or Database Catalogs at the same time fails
- Problem: Upgrading multiple Hive and Impala Virtual Warehouses or Database Catalogs at the same time fails.
