新建了一个kafka集群,在window下写了一个简单的producer做测试,结果遇到了消息发送失败的问题,代码如下:
Properties props = new Properties(); props.put("metadata.broker.list", "192.168.1.107:6667"); props.put("serializer.class", "kafka.serializer.StringEncoder"); // props.put("partitioner.class", "example.producer.SimplePartitioner"); props.put("request.required.acks", "1"); ProducerConfig config = new ProducerConfig(props); Producer producer = new Producer<String, String>(config); String payload = String.format("ayuananybc%s", "test"); KeyedMessage<String, String> data = new KeyedMessage<String, String>("mytopic", payload); producer.send(data);
经过查看kafka broker的参数如下:
于是猜测是不是本地运行的时候不认识Slave1(192.168.1.107)? 然后我在hosts中加上:192.168.1.107 Slave1。
结果就可以了:
其实原因是让kafka知道zookeeper的监听地址,我们不修改hosts,加上如下配置也是可以的:
