             Summary: GKE kafka-consumer-groups returns incorrect hosts
                 Key: KAFKA-13961
                 URL: https://issues.apache.org/jira/browse/KAFKA-13961
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 2.8.1
            Reporter: Mikhail Filatov


Hello,

We faced with strange behavior on Google Kubernetes Engine with kafka-consumer-groups.sh script:
{code:java}
./bin/kafka-consumer-groups.sh -bootstrap-server "localhost:9093" --command-config ${KAFKA_HOME}/bin/adminclient.properties --describe --group group{code}
Script returned results successfully, but host column value is incorrect: instead of particular consumer host we have GKE node ip. Hadn't luck to find, how describeGroup request managed, so asking for your suggestions.

Could it be connected with some GKE configuration (LoadBalancer or something like that)? On other clouds we haven't faced such behavior.
