You want to process data flows on the Stream service nodes, but the data flow runs stop. The status of the Stream service nodes is Normal.
The Kafka broker in the Stream service is not available for all of the Stream service nodes. Pega Platform must have access to all Kafka broker ports in the cluster.
- Ensure that your cluster nodes can communicate on port 9092.
- If you experience conflicts with other processes on your Pega Platform instance, change the
pyBrokerPort configuration entry in the
prconfig.xmlfile by adding an entry similar to this example:where port_number is a port that does not cause conflicts in your configuration.
<env name="dsm/services/stream/pyBrokerPort" value="port_number"/>
