windows - Kafka: unable to start Kafka - process can not access file 00000000000000000000.timeindex

Question

Kafka enthusiast, need little help here. I am unable to start kafka because the file 0000000000000000000.timeindex is being used by another process. Below are the logs:

[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: installationkafka_2.11-0.11.0.0logest-00000000000000000000.timeindex: The process cannot access the file because it is being used by another process.

Answer 1

I had the same issue. The only way I could figure it out that was just delete the C:mpkafka-logs directory. After that i was able to start up the kafka server.

You will lose your data and the offset will start from 0.
