Question

连接到 kafka 代理时出现错误，融合控制台日志显示此错误。

我在kafka服务器上的配置如下:

listeners=PLAINTEXT://:9092,SSL://:9093

# Broker security settings
ssl.truststore.location=/home/xcode/Descargas/ssl/server.truststore.jks
ssl.truststore.password=123456
ssl.keystore.location=/home/xcode/Descargas/ssl/server.keystore.jks
ssl.keystore.password=123456
ssl.key.password=123456
ssl.client.auth=required
security.inter.broker.protocol=SSL

我尝试使用kafka-pyton包的KafkaClient执行操作，返回如下错误。

assert broker, 'Broker id %s not in current metadata' % node_id
AssertionError: Broker id None not in current metadata

问题解决了，是证书生成不正确的问题，使用一些测试证书就可以了。这些是您使用的证书，您也可以在该存储库中看到服务器设置。 https://github.com/aggress/confluent-kafka-vagrant-ansible
