可能的副本
Kafka - This server is not the leader for that topic-partition
但没有公认的答案,也没有明确的解决方案。
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));
我得到以下例外:
Exception in thread "main" java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.NotLeaderForPartitionException: This server is not the leader for that topic-partition.

当我试着
kafka-console-producer
,我得到以下错误:
D:\kafka_2.11-0.10.2.0\bin\windows>kafka-console-producer.bat --broker-list localhost:9092 --topic My_Topic

那么上述步骤就可以很好地工作了。
我该怎么改正
My_Topic
