Kafka发送超过broker限定大小的消息时Client和Broker端各自会有什么异常?

Kafka发送超过broker限定大小的消息时Client和Broker端各自会有什么异常?

前几天遇到一个bug,查看发送日志发现java.io.IOException: Broken pipe的错误,通过深入了解发现当kafka producer发送的消息体大于Broker配置的默认值时就会报这个异常。如果仅发送一次是不会报这个异常的,要连续发送才会报这个异常。

本博文记录一下当Kafka发送超过broker限定大小的消息时Client和Broker端各自会有什么异常。

Kafka Broker Configs中有一个参数:message.max.bytes——用来指定消息的大小。

当Producer向Broker发送一个比Kafka Broker配置的阈值还要大的一个消息时,Producer端和Broker端会有什么异常情况。

Producer端测试代码:

public class Producer {

public static final String brokerList = "xx.xx.197.59:9092";
public static final String topic = "versionTopic";

public static void main(String[] args) {
Properties properties = new Properties();
properties.put("serializer.class", "kafka.serializer.StringEncoder");
properties.put("metadata.broker.list", brokerList);

ProducerConfig config = new ProducerConfig(properties);
kafka.javaapi.producer.Producer producer = new kafka.javaapi.producer.Producer<Integer, String>(config);

String message = getMessage(1 * 1024 * 1024);

for(int i=0;i<3;i++) {
KeyedMessage<Integer, String> keyedMessage = new KeyedMessage<Integer, String>(topic, message);
producer.send(keyedMessage);
System.out.println("=============================");
}

try {
TimeUnit.SECONDS.sleep(50);
} catch (InterruptedException e) {
e.printStackTrace();
}

}

public static String getMessage(int msgSize) {
StringBuilder stringBuilder = new StringBuilder();
for(int i=0;i<msgSize;i++) {
stringBuilder.append("x");
}
return stringBuilder.toString();
}
}

Producer端输出:

注意输出中的:kafka.common.MessageSizeTooLargeException: Message size is 1048602 bytes which exceeds the maximum configured message size of 1000012.这句。


注意:当kafka一切正常,producer端发送也会出现这样的INFO:

(之后producer发送数据)

看倒数三行,咋一看以为是出了异常,但事实上这是正常的INFO, 至于为什么先Connected又Disconnecting又Connected那就不得而知了,等博主翻阅了kafka的源码之后再来解释这个现象咯~
