Kafka Failed to update metadata

问题

I am using Kafka v0.10.1.1 with Spring-boot.

I am trying to produce a message in a Kafka topic mobile-user using the below producer code:

Topic mobile-user have 5 partitions and 2 replication factor. I have attached my Kafka settings at the end of the question.

package com.service;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.kafka.support.SendResult;
import org.springframework.stereotype.Service;
import org.springframework.util.concurrent.ListenableFuture;
import org.springframework.util.concurrent.ListenableFutureCallback;

import com.shephertz.karma.constant.Constants;
import com.shephertz.karma.exception.KarmaException;
import com.shephertz.karma.util.Utils;

/**
 * @author Prakash Pandey
 */
@Service
public class NotificationSender {

    @Autowired
    private KafkaTemplate<String, String> kafkaTemplate;

    private static Logger LOGGER = LoggerFactory.getLogger(NotificationSender.class);

    // Send Message
    public void sendMessage(String topicName, String message) throws KarmaException {
        LOGGER.debug("========topic Name===== " + topicName + "=========message=======" + message);
        ListenableFuture<SendResult<String, String>> result = kafkaTemplate.send(topicName, message);
        result.addCallback(new ListenableFutureCallback<SendResult<String, String>>() {
            @Override
            public void onSuccess(SendResult<String, String> result) {
                LOGGER.info("sent message='{}'" + " to partition={}" + " with offset={}", message,
                        result.getRecordMetadata().partition(), result.getRecordMetadata().offset());
            }

            @Override
            public void onFailure(Throwable ex) {
                LOGGER.error(Constants.PRODUCER_MESSAGE_EXCEPTION.getValue() + Utils.getStackTrace(ex));

            }
        });

        LOGGER.debug("Payload sent to kafka");
        LOGGER.debug("topic: " + topicName + ", payload: " + message);
    }
}

Problem:

I am successfully able to sent message to kafka but sometimes I am receiving this error:

org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after 5000 ms.
2017-10-25 06:21:48, [ERROR] [karma-unified-notification-dispatcher - NotificationDispatcherSender - onFailure:43] Exception in sending message to kafka for queryorg.springframework.kafka.core.KafkaProducerException: Failed to send; nested exception is org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after 5000 ms.

It would be very helpful if you could help me solving this problem. Thanks.

Please note: I am not receiving this above message every time. I am successfully able to produce a message to kafka-topic and successfully consume it on consumer. This above error comes approxmately after 1000 successfully produced message.

Change default bootstrap-servers property:

private List<String> bootstrapServers = new ArrayList<String>(
            Collections.singletonList("localhost:9092"));

to yours:

spring.kafka.bootstrap-servers: ${kafka.binder.broker}:${kafka.binder.defaultBrokerPort}
