I have a HDP 2.2.6 cluster that includes three Kafka brokers. The machines where the brokers are installed have two network interfaces each. Interface A faces “outward” towards other services, and interface B faces “inward” where all the HDP-related services exist. The Kafka-machines were added to the cluster through Ambari using interface B. However, we would like to receive messages from produces on interface A as well as interface B.
Is it possible to configure Kafka to listen for messages on both interfaces? Or, if need be, can Kafka be configured to just listen for messages on interface A, which is not the interface/hostname where the host was added to the cluster?
