KAFKA - 错误由于（kafka.server.BrokerMetadataCheckpoint）而无法写入meta.properties

Question

我在Windows10上搭建Kafka源码读取环境，出现如下错误，请问这是怎么回事，我是刚学kafka的人

[2021-04-29 19:57:42,957] ERROR Failed to write meta.properties due to (kafka.server.BrokerMetadataCheckpoint)

和下面的另一个错误

Answer 1

我降级到 Kafka 2.8.1 版本（https://dlcdn.apache.org/kafka/2.8.1），之后一切正常。

Answer 2

这是发生日志保留时的常见错误。版本并不重要。

Kafka 对 Windows 文件系统没有很好的支持。

您可以使用 WSL2 或 Docker 来解决这些限制 - https://www.confluence.io/blog/set-up-and-run-kafka-on-windows-linux-wsl-2/
