mesos – 无法在DCOS上安装Kafka

2023年8月31日 291次阅读

在没有任何自定义配置的DCOS上安装Kafka会提供以下日志

群集配置是：

8个私人节点,
2个公共节点

24个核心总数,
320 GB Ram总计

所有资源都是免费的.

标准输出：

log4j:WARN No appenders could be found for logger (org.jboss.logging).  
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

标准输出：

最佳答案 按照此处的说明修复了问题：
https://docs.mesosphere.com/1.8/usage/service-guides/kafka/uninstall

要全新安装Kafka包我们首先需要清理
它以前来自Zookeeper的州.只需从GUI或CLI卸载它就不起作用,卸载后从zookeeper中清除先前的状态,然后再进行全新安装.
