控制台生产者中的领导者不可用 Kafka [英] Leader Not Available Kafka in Console Producer

问题描述

我正在尝试使用 Kafka.
所有配置都正确完成，但是当我尝试从控制台生成消息时，我不断收到以下错误

WARN 获取相关 ID 为 39 的元数据时出错:{4-3-16-topic1=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)

Kafka 版本:2.11-0.9.0.0

解决方案

它可能与 server.properties 中的 advertised.host.name 设置有关.

可能发生的情况是，您的生产者试图找出给定分区的领导者，找出其 advertised.host.name 和 advertised.port并尝试连接.如果这些设置没有正确配置，那么它可能会认为领导者不可用.

I am trying to use Kafka.
All configurations are done properly but when I try to produce message from console I keep getting the following error

WARN Error while fetching metadata with correlation id 39 : 
     {4-3-16-topic1=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)

Kafka version: 2.11-0.9.0.0

解决方案

It could be related to advertised.host.name setting in your server.properties.

What could happen is that your producer is trying to find out who is the leader for a given partition, figures out its advertised.host.name and advertised.port and tries to connect. If these settings are not configured correctly it then may think that the leader is unavailable.
