Kafka is giving: "The group member needs to have a valid member id before actually entering a consumer group"

I am using Kafka to consume messages in Java. I want to test by starting the same app multiple times on my local box. When I start up, the first time I am able to start consuming messages from the topic. When I start up a second one I get:

Join group failed with org.apache.kafka.common.errors.MemberIdRequiredException: The group member needs to have a valid member id before actually entering a consumer group

and dont get any messages from the topic. If I try to start more of them I get the same issues.

The configuration I am using for Kafka is

spring:
  kafka:
    bootstrap-servers: kafka:9092
    consumer:
      auto-offset-reset: earliest
      key-deserializer: org.springframework.kafka.support.serializer.ErrorHandlingDeserializer2
      value-deserializer: org.springframework.kafka.support.serializer.ErrorHandlingDeserializer2
      properties:
        spring.deserializer.key.delegate.class: org.springframework.kafka.support.serializer.JsonDeserializer
        spring.deserializer.value.delegate.class: org.springframework.kafka.support.serializer.JsonDeserializer
        spring.json.use.type.headers: false
    listener:
      missing-topics-fatal: false

I have two topics

@Configuration
public class KafkaTopics {
    @Bean("alertsTopic")
    public NewTopic alertsTopic() {

        return TopicBuilder.name("XXX.alerts")
            .compact()
            .build();
    }

    @Bean("serversTopic")
    public NewTopic serversTopic() {

        return TopicBuilder.name("XXX.servers")
            .compact()
            .build();
    }

}

And two listeners in different class files.

@KafkaListener(topics = SERVERS_KAFKA_TOPIC, id = "#{T(java.util.UUID).randomUUID().toString()}",
    properties = {
        "spring.json.key.default.type=java.lang.String",
        "spring.json.value.default.type=com.devhaus.learningjungle.db.kafka.ServerInfo"
    })
public void registerServer(
    @Payload(required = false) ServerInfo serverInfo
) 

@KafkaListener(topics = ALERTS_KAFKA_TOPIC,
    id = "#{T(java.util.UUID).randomUUID().toString()}",
    properties = {
        "spring.json.key.default.type=com.devhaus.learningjungle.db.kafka.AlertOnKafkaKey",
        "spring.json.value.default.type=com.devhaus.learningjungle.db.kafka.AlertOnKafka"
    })
public void processAlert(
    @Header(KafkaHeaders.RECEIVED_MESSAGE_KEY) AlertOnKafkaKey key,
    @Header(KafkaHeaders.RECEIVED_PARTITION_ID) int partitionId,
    @Header(KafkaHeaders.OFFSET) long offset,
    @Payload(required = false) AlertOnKafka alert)

From my analysis. This is normal behaviour, you can change the log levels to exclude it.

The reason for this is if the server detects that the client can support member.id it will give that error back to the client. This is noted in KIP-394.

The client will then reconnect back to the server with a generated member ID.

I encountered the same issue, also preventing my consumer from subscribing to certain topics.

I figured that the member.id might be similar to the client-id (using Camel here), which might be in some way related to the consumer group.

What fixed it for me is a changed, this time non-changing client-id for my consuming service, leaving the same consumer group as is.

hummm....in my case, consumers will rejoin the group with a generated ID. Here is my test and result. FYI

@Test
    void testSyncSend() throws ExecutionException, InterruptedException {
        int id = (int)(System.currentTimeMillis()/1000);
        SendResult result = producer.syncSend(id);
        logger.info("[testSyncSend] id:{}, result:{}", id, result);
        new CountDownLatch(1).await();
    }
