我有一个单节点,多(3)个代理zookeeper/kafka设置。我使用的是kafka0.10java客户端。
我编写了以下简单的远程(与kafka不同的服务器上)producer(在代码中我用myip替换了我的公共ip地址):
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个代理的服务器属性如下所示(在3个不同的服务器属性文件中,broker.id为0、1、2,侦听器为纯文本://:9092、纯文本://:9093、纯文本://: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:
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
执行代码时,出现以下异常:

有人知道我错过了什么吗?任何帮助都将不胜感激。谢谢
3条答案
按热度按时间monwx1rj1#
端口信息
BOOTSTRAP_SERVERS_CONFIG
配置不正确(myip:9092).正如您在server.properties中提到的“纯文本://:9093,纯文本://:9093,纯文本://:9094”。

我也遇到同样的问题。
您应该更改kafka server.properties以指定ip地址。如:
PLAINTEXT://YOUIP:9093
如果没有,Kafka将使用主机名,如果制作者不能得到主机,它就不能发送消息给Kafka,即使你可以telnet他们。pod7payv3#
这个答案与我们有一些共同的见解。您可以增加request.timeout.ms producer配置,这将允许客户端在批处理过期之前将其排队更长时间。
您可能还希望查看batch.size和linger.ms配置,并找到适合您的情况的最佳配置。
