錯誤日誌：

org.apache.kafka.common.errors.TimeoutException: Batch containing 100 record

kafka版本：0.10.0.1

zookeeper版本: 3.4.5

產生的現象:

編寫好java客戶端後,給kafka傳送資料,可是資料會一直髮送不過去,而且顯示上面那種TimeoutException錯誤.

生產者配置:

import java.util.Properties;

import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.Producer;
import org.apache.kafka.clients.producer.ProducerRecord;


public class KafkaProducerTest{
	 public static void main(String[] args) {
		 Properties props = new Properties();
		 props.put("bootstrap.servers", "192.168.72.18:9092");
		 props.put("acks", "all");
		 props.put("retries", 0);
		 props.put("batch.size", 16384);
		 props.put("linger.ms", 1);
		 props.put("buffer.memory", 33554432);
		 props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
		 props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

		 Producer<String, String> producer = new KafkaProducer<String, String>(props);
		 for(int i = 0; i < 100; i++){
			 System.out.println(Integer.toString(i));
		     producer.send(new ProducerRecord<String, String>("test1001", Integer.toString(i), Integer.toString(i)));
		 }
		 producer.close();
	}
}
 

消費者程式碼:

import java.util.Arrays;
import java.util.Properties;

import org.apache.kafka.clients.consumer.ConsumerRecord;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.KafkaConsumer;

public class KafkaConsumerTest {
	public static void main(String[] args) {
		 Properties props = new Properties();
	     props.put("bootstrap.servers", "192.168.72.18:9092");
	     props.put("group.id", "test");
	     props.put("enable.auto.commit", "true");
	     props.put("auto.commit.interval.ms", "1000");
	     props.put("session.timeout.ms", "30000");
	     props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
	     props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
	     KafkaConsumer<String, String> consumer = new KafkaConsumer<String, String>(props);
	     consumer.subscribe(Arrays.asList("test1001"));
	     while (true) {
	         ConsumerRecords<String, String> records = consumer.poll(100);
	         for (ConsumerRecord<String, String> record : records)
	             System.out.printf("offset = %d, key = %s, value = %s", record.offset(), record.key(), record.value());
	     }
	}
}
 

解決:

最終是傳送配置應該不正確，原來的配置：

# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0

############################# Socket Server Settings #############################

# The address the socket server listens on. It will get the value returned from
# java.net.InetAddress.getCanonicalHostName() if not configured.
#   FORMAT:
#     listeners = security_protocol://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092
#listeners=PLAINTEXT://:9092
listeners=PLAINTEXT://name1:9092

# Hostname and port the broker will advertise to producers and consumers. If not set,
# it uses the value for "listeners" if configured.  Otherwise, it will use the value
# returned from java.net.InetAddress.getCanonicalHostName().
#advertised.listeners=PLAINTEXT://your.host.name:9092
advertised.listeners=PLAINTEXT://name1:9092

# The number of threads handling network requests
num.network.threads=3
 

修改後的配置：

# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0

# The address the socket server listens on. It will get the value returned from

這樣把ip寫好，不使用名字對映，就正常了
