Question

我已经付出了一些努力让Kafka在Windows 32上运行（公司发行的笔记本电脑 - 肯定不是我的选择......）。

我成功地创建了一些主题。但是在停止/重启kafka之后，它无法重新阅读这些主题。这是启动日志

现在我可以删除/重新创建主题。作为调查的一部分，我实际上已经多次这样做了（例如确保没有Zookeeper损坏），如果有关如何在这个过时的操作系统上获得kafka服务器的任何提示将不胜感激。

错误解释log.dir是unix和windows中kafka痛苦的巨大根源。

似乎异常是由以下声明引起的划分。 replicaManager.highWatermarkCheckpoints（log.dir.getParent）它试图在highWatermarkCheckpoint文件的地图中查找键“\ kafka8-tmp \ kafka-logs”，但它不存在。我们注册使用log.dirs中的属性值的键。

确保你没有尾部斜杠，并且new java.io.File("\tmp\kafka-logs").getParent没有失真（我旁边没有Windows机器可以自己找出所有这些前/后斜线）。

Kafka无法在Windows上启动 - 找不到密钥：\ tmp \ kafka-logs
