I\'m new to Kafka and am trying to use the AdminClient API to manage the Kafka server running on my local machine. I have it setup exactly the same as in the quick

    Sounds like your broker isn't healthy...

    This code works fine

    public class Main {
    
        static final Logger logger = LoggerFactory.getLogger(Main.class);
    
        public static void main(String[] args) {
            Properties properties = new Properties();
            properties.setProperty(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
            properties.setProperty(AdminClientConfig.CLIENT_ID_CONFIG, "local-test");
            properties.setProperty(AdminClientConfig.RETRIES_CONFIG, "3");
    
            try (AdminClient client = AdminClient.create(properties)) {
                final CreateTopicsResult res = client.createTopics(
                        Collections.singletonList(
                                new NewTopic("foo", 1, (short) 1)
                        )
                );
                res.all().get(5, TimeUnit.SECONDS);
            } catch (InterruptedException | ExecutionException | TimeoutException e) {
                logger.error("unable to create topic", e);
            }
        }
    }
    

    And I can see in the broker logs that the topic was created

    I started kafka service with bitnami/kafka, and got exactly the same error. Try to start kafka by this version, it works: https://hub.docker.com/r/wurstmeister/kafka

    $ docker run -d --name zookeeper-server --network app-tier \
      -e ALLOW_ANONYMOUS_LOGIN=yes  -p 2181:2181 zookeeper:3.6.2
    
    $ docker run -d --name kafka-server --network app-tier --publish 9092:9092 \
      --env KAFKA_ZOOKEEPER_CONNECT=zookeeper-server:2181 \
      --env KAFKA_ADVERTISED_HOST_NAME=30.225.51.235 \
      --env KAFKA_ADVERTISED_PORT=9092  \
      wurstmeister/kafka
    

    30.225.51.235 is ip address for the host machine.
