Question

我需要使用log4j2.xml配置Kafka appender，设置工作正常本地，但服务器我收到以下错误。

本地卡夫卡：kafka_2.11-0.10.2.0

Kafka Appender：0.9.0.0 当地工作得很好。

服务器Kafka：0.8

Kafka Appender：0.9.0.0

在服务器上我收到以下错误：

Answer 1

您无法获取元数据，检查kafka群集是否已启动并且运行且没有连接问题

Answer 2

我的不好，我为log4j2.xml中的额外空间写了bootstrap.servers属性的值，删除空格后，我可以连接到Kafka。感谢。

Apache Kafka 0.8 log4j2.xml appender收到超时错误
