Cloudera Operational Database 1.27 version supports JWT authentication, provides Data Lake templates while creating a database, and a CLI option to enable HBase region canaries.

Cloudera Operational Database supports configuring JWT authentication for your HBase clients

Cloudera Operational Database now allows you to configure JWT (JSON Web Token)-based authentication for your HBase clients, which uses an unique identifier and is a standard way of securely transmitting signed information between two parties. To know more about the JWT authentication, see Configuring JWT authentication for HBase client.

Cloudera Operational Database supports creating an operational database using a predefined Data Lake template

When you create an operational database, you can now define the structure of your database based on a predefined Data Lake template. The template defines the number of gateway, master, and worker nodes to be added while creating a database.

You can select a template and accordingly the nodes are added into the Cloudera Operational Database cluster after the database is successfully created.

To know more about this, see Creating a database using Cloudera Operational Database.

Cloudera Operational Database provides a CLI option to enable HBase region canaries

Cloudera Operational Database now provides a CLI option, --enable-region-canary to enable the HBase region canaries while creating an operational database.

Use the following command to enable the HBase region canaries.

cdp opdb create-database --environment-name ENVIRONMENT_NAME --database-name DATABASE_NAME --enable-region-canary

hbase_region_health_canary_enabled
