Issue on external service (Kafka)

[tittuvarghese]

There is some issue with exposing the NodePort for outside access in Kafka. It's refusing the connection even though the service is up and running as per the logs.

[root@AWSB outside-services]# kubectl logs -n kafka kafka-1 2>&1 | grep 9094
        listeners = PLAINTEXT://:9092,OUTSIDE://:9094
        listeners = PLAINTEXT://:9092,OUTSIDE://:9094

Could #187 be related? It's quite possible that general purpose outside access must be outside the scope of this project. Obviously it's also possible that you've stumbled upon a regression. If you think so please state which branch or commit you applied from.
