This release of the Data Hub service introduces the following changes:
Streams Messaging High Availability clusters now include highly available Knox (October 30, 2023)
The Streams Messaging High Availability cluster configuration is updated. The configuration now includes a highly available Knox service. Specifically, a new host group called manager is introduced. This host group is not scalable and includes two nodes. Both nodes host a Knox service instance. In addition, Cloudera Manager is moved from the master host group and is now deployed on one of the manager nodes. The master host group now only includes Cruise Control and Streams Messaging Manager.
The previous cluster configuration is no longer available. Streams Messaging High Availability clusters provisioned at a previous date will continue to run using the old configuration. Updating an existing cluster to use the new configuration is not possible. For more information, see Streams Messaging cluster layout.
