This release of Cloudera Data Warehouse (CDW) service on CDP Private Cloud Data Services introduces the new features and improvements that are described in this section.

CDW supports MySQL database for HMS on the base cluster

The Hive Metastore (HMS) on the CDP private base cluster supports MySQL databases in addition to PostgreSQL and MariaDB. For more information on database requirements, see Base cluster database requirements for Cloudera Data Warehouse Private Cloud.

Users can access Hue using SSO

After logging in to the CDP Management Console, you can automatically log in to Hue using Single-Sign On (SSO). You do not need to enter your credentials to access Hue. To use this feature, you must first upgrade the CDW service to 1.3.3 (if you are on a previous version) and also create a new Virtual Warehouse. Upgrading an existing Virtual Warehouse to a newer version does not enable SSO authentication for Hue. The first user logging in to Hue will be a superuser.

CDW supports encrypted HDFS

CDW components such as Hive, Impala, and Hue can now read and write encrypted data stored on HDFS on the base cluster. If you are using Impala on an encrypted source data, then ensure that the data written to disk temporarily during processing is encrypted to keep the data confidential even during processing. For more information, see Configuring Impala Virtual Warehouses to spill encrypted data to HDFS in CDW Private Cloud.

Support for using Hive user-defined functions (UDF) (Technical Preview)

You can export user-defined functions (UDF) to a JAR file from a Hadoop- and Hive-compatible Java project and store the JAR file on HDFS. Using Hive commands, you can register the UDF based on the JAR file, and call the UDF from a Hive query using Hue in CDW. For more information, see Creating a user-defined function in Cloudera Data Warehouse.

Support for creating Impala tables in Kudu (Technical Preview)

You can configure an Impala Virtual Warehouse to connect to Kudu and create Impala tables in Kudu using the Hue query editor. For more information, see Configuring Impala Virtual Warehouses to create Impala tables in Kudu in Cloudera Data Warehouse Private Cloud.

Support for using custom generated Kerberos keytabs (Technical Preview)

By default, the principals and keytabs in CDW are generated programmatically. You can generate and provide the keytabs, but the hostnames in the Kerberos principals are fixed. To learn more about this, see Predefined Kerberos principals in Cloudera Data Warehouse Private Cloud.

Security improvements

  • CVE-2021-44228 (Apache Log4j 2 vulnerability) has been addressed in CDW on CDP Private Cloud 1.3.3 by upgrading Apache Log4j 2 to version 2.16.
  • CDP now sets stricter file permissions for CDW secrets.
