Creating HDF Messaging Management clusters
When creating a Messaging Management cluster from the default blueprint, make sure to follow these guidelines.
- On the Hardware and Storage page, place the Ambari Server on the “Services” host group.
- When creating a cluster, open 3000 TCP port on the Services host group for Grafana.
- Adding nodes to the host group including Kafka broker (via resizing or autoscaling) is not supported. Nevertheless, it can be achieved by using the following workaround: After scaling the host group, use Ambari to add Kafka broker to each newly added node.
