What's New in Streams Messaging

Learn about the new Streams Messaging features in Cloudera DataFlow for Data Hub 7.2.9.

Kafka

Kafka metrics endpoints can be secured

TLS/SSL encryption as well as Basic Authentication can now be enabled for the HTTP endpoints of Kafka metrics.

TLS/SSL encryption can be enabled with the SSL Encryption For HTTP Metric Reporter property. However, this property does not take effect on its own, TLS/SSL must be enabled for the Kafka broker for this property to work.

Basic Authentication can be enabled with the Enable HTTP Metric Report Basic Authentication property. In addition to enabling Basic Authentication, you also need to set a username and password used for authentication. These can be configured with the HTTP Metric Report User and HTTP Metric Report Password properties respectively.

For more information regarding these properties, see Kafka Properties in Cloudera Runtime.

Schema Registry

Import tool for Confluent Schema Registry
You can now import schemas from Confluent Schema Registry's Kafka topic dump. The schemas need to be uploaded as a file to Schema Registry via REST.

The Ranger model was modified and a new permission for "export-import" was added. When authorization is enabled, users need to have the Create permission under "export-import" in order to import the schemas.

For more information, see Importing Confluent Schema Registry schemas into Cloudera Schema Registry.
