【问题描述】:
Kafka - This server is not the leader for that topic-partition 可能重复,但没有公认的答案,也没有明确的解决方案。
我有一个简单的 java 程序来向 Kafka 生成消息:
Properties props = new Properties();
props.put("bootstrap.servers", "localhost:9092");
props.put("acks", "all");
props.put("retries", 1);
props.put("batch.size", 16384);
props.put("linger.ms", 100);
props.put("buffer.memory", 33554432);
props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
props.put("value.serializer", "com.company.project.KafkaValueSerializer");
MyMessage message = new MyMessage();
Producer<String, MyMessage> producer = new KafkaProducer<>(props);
Future<RecordMetadata> future =
producer.send(new ProducerRecord<String, MyMessage>("My_Topic", "", message));
我收到以下异常:
Exception in thread "main" java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.NotLeaderForPartitionException: This server is not the leader for that topic-partition.
at org.apache.kafka.clients.producer.internals.FutureRecordMetadata.valueOrError(FutureRecordMetadata.java:94)

at
Caused by: org.apache.kafka.common.errors.NotLeaderForPartitionException: This server is not the leader for that topic-partition.
当我尝试使用 kafka-console-producer 时,我收到以下错误:
D:\kafka_2.11-0.10.2.0\bin\windows>kafka-console-producer.bat --broker-list localhost:9092 --topic My_Topic
hello

当我描述我的主题时,我有以下信息:
Topic:My_Topic PartitionCount:1 ReplicationFactor:1 Configs:
Topic: My_Topic Partition: 0 Leader: 0 Replicas: 0 Isr: 0
我尝试创建一个新主题并生成Quick start guide 中提到的消息,然后上述步骤运行良好。
我应该在My_Topic或生产者配置中进行哪些更正,以便我可以在该主题中成功发布消息?
【问题讨论】:
-
您可以尝试增加重试次数并告诉我结果吗?例如`props.put("retries", 10);`
-
@GiorgosMyrianthous:没有任何改变。它仍然具有相同的异常和堆栈跟踪。
