Advanced configurations in CDW Private Cloud
You can access advanced configurations in Cloudera Data Warehouse (CDW) Private Cloud from the left navigation pane on the CDW web interface. Some of these configurations must be enabled before you activate an environment and some can be applied by refreshing the environment, Database Catalog, and Virtual Warehouses.
| Configuration | Description | Enabled by default? | Condition for applying the configuration |
|---|---|---|---|
| Create databases for Virtual Warehouses | Enables the automatic creation of databases for Hue and HMS. For external tables, CDW requires permission for CREATE and DROP DATABASE operations. If disabled, you need to create the databases before creating Database Catalogs.** | No | Enable before activating an environment in CDW. |
| Use deterministic namespace names | Makes the namespace names deterministic, that is, given the same input, a client can get to the same name every time. Enable this option if you need to create Kerberos principals and keytabs. | Yes | Enable before activating an environment in CDW. |
| Enable ADLS as a storage provider | Enables you to use Azure Data Lake Storage (Gen1 and Gen2) for storing tables. | Yes | Refresh |
| Copy configurations from base cluster to CDW | Configurations such as default file format, compression type, and transactional type are copied from the base cluster to CDW to aid cluster setup and workload migration. | Yes | Refresh* |
| Customize pod sizes | Enables you to customize the number of resources allocated to the Impala coordinators, executors, and catalog daemons. | Yes | No special action needed. |
| Store logs on HDFS | Enables you to store CDW logs to HDFS on the base cluster. | Yes | Refresh* |
| Create multiple Database Catalogs | Enables you to create more than one custom Database Catalogs for your
environment. Not recommended for production deployments. |
No | No special action needed. |
| Enable S3 and S3-compatible object store providers | Enables you to use AWS S3 and other similar, compatible, on-premises object stores that support the S3 protocol for storing tables. | Yes | Refresh* |
| Enable warehouse-level access control for Impala | Enables you to allow access to an Impala Virtual Warehouse for selected user groups. This option is not available for Unified Analytics. | Yes | Refresh* |
| Enable workload-aware autoscaling for Impala | Enables you to create multiple executor group sets of different sizes that can
scale independently based on the load. This is a preview feature. Not recommended for production deployments. |
No | Refresh* |
**
This option is available only if you are upgrading CDP Private Cloud Data Services from a previous release.
If you enable this option, then you must specify the external database name on the Activate Environment page.
* Refresh the environment, Database Catalog,
and Virtual Warehouses, in this order.
