[2018-10-29 17:41:54,070] WARN [Controller-0-to-broker-1-send-thread], Controller 0's connection to broker kafka-1.kafka.default.svc.cluster.local:9093 (id: 1 rack: null) was unsuccessful (kafka.controller.RequestSendThread) java.io.IOException: Connection to kafka-1.kafka.default.svc.cluster.local:9092 (id: 1 rack: null) failed

Service object in kafka.yaml :
