windows - Kafka : unable to start Kafka - process can not access file 00000000000000000000. 时间索引

Question

Kafka 爱好者，这里几乎不需要帮助。我无法启动 kafka，因为文件 \00000000000000000000.timeindex 正在被另一个进程使用。以下是日志:

[2017-08-09 22:49:22,811] FATAL [Kafka Server 0], Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
java.nio.file.FileSystemException: \installation\kafka_2.11-0.11.0.0\log\test-0\00000000000000000000.timeindex: The process cannot access the file because it is being used by another process.

我遇到了同样的问题。我唯一能弄清楚的方法就是删除 C:\tmp\kafka-logs 目录。之后我就可以启动 kafka 服务器了。

您将丢失您的数据，偏移将从0开始。
