Kafka 0.10 Java客户端TimeoutException：包含1条记录的批处理已过期 [英] Kafka 0.10 Java Client TimeoutException: Batch containing 1 record(s) expired

问题描述

我有一个单节点，多（3）个代理Zookeeper / Kafka设置。我正在使用Kafka 0.10 Java客户端。

I have a single node, multi (3) broker Zookeeper / Kafka setup. I am using the Kafka 0.10 Java client.

我写了以下简单的远程（在与Kafka不同的服务器上）生产者（在代码中我用MYIP替换了我的公共IP地址） ）：

I wrote following simple remote (on a different Server than Kafka) Producer (in the code I replaced my public IP address with MYIP):

Properties config = new Properties();
try {
    config.put(ProducerConfig.CLIENT_ID_CONFIG, InetAddress.getLocalHost().getHostName());
    config.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "MYIP:9092, MYIP:9093, MYIP:9094");
    config.put(ProducerConfig.ACKS_CONFIG, "all");
    config.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringSerializer");
    config.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.ByteArraySerializer");
    producer = new KafkaProducer<String, byte[]>(config);
    Schema.Parser parser = new Schema.Parser();
    schema = parser.parse(GATEWAY_SCHEMA);
    recordInjection = GenericAvroCodecs.toBinary(schema);
    GenericData.Record avroRecord = new GenericData.Record(schema);
    //Filling in avroRecord (code not here)
    byte[] bytes = recordInjection.apply(avroRecord);

    Future<RecordMetadata> future = producer.send(new ProducerRecord<String, byte[]>(datasetId+"", "testKey", bytes));
    RecordMetadata data = future.get();
} catch (Exception e) {
    e.printStackTrace();
}

3个经纪人的服务器属性如下所示（在3个不同的服务器中）属性文件broker.id为0,1,2，侦听器为PLAINTEXT：//：9092，PLAINTEXT：//：9093，PLAINTEXT：//：9094，host.name为10.2.0.4,10.2.0.5,10.2.0.6 ）。
这是第一个服务器属性文件：

My server properties for the 3 brokers look like this (in the 3 different server properties files broker.id is 0, 1, 2 and listeners is PLAINTEXT://:9092, PLAINTEXT://:9093, PLAINTEXT://:9094 and host.name is 10.2.0.4, 10.2.0.5, 10.2.0.6). This is the first server properties file:

broker.id=0
listeners=PLAINTEXT://:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/tmp/kafka1-logs
num.partitions=1
num.recovery.threads.per.data.dir=1
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000

当我执行代码时，我得到以下异常：

When I execute the code, I get following exception:

java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.TimeoutException: Batch containing 1 record(s) expired due to timeout while requesting metadata from brokers for 100101-0

有谁知道我错过了什么？任何帮助，将不胜感激。非常感谢

Does anyone know what I am missing? Any help would be appreciated. Thanks a lot

推荐答案

我遇到同样的问题。

你应该更改您的kafka server.properties以指定IP地址。
例如：

You should change your kafka server.properties to specify ip address. eg:

PLAINTEXT：// YOUIP ：9093

PLAINTEXT://YOUIP:9093

如果没有，kafka将使用主机名，如果生产者无法获得主机，即使你可以远程登录它也无法向kafka发送消息。

if not, kafka will use hostname, if the producer can not get the host, it can not send message to kafka even if you can telnet them.
