Kafka Broker

[#1]

Hi,

I have these errors in my  cloudera manager.

General Error(s)

• Port conflict detected: 9092 (TCP Port) is also used by: Kafka Broker (instance-1-cdh-hadoop). 
• Port conflict detected: 9092 (Advertised Port) is also used by: Kafka Broker (instance-1-cdh-hadoop). 

I'm also unable to consume messages after running producer/consumer on a single node.

I have the following properties:

Hello @Moutasem ,

Thank you for posting your query.

From the Error messages posted, it looks the agent complains on ports as it detects the conflicting usage of port between 2 services. Do you have multiple Kafka services (Like different set of Kafka brokers) added and managed by same Cloudera Manager ?
