Kafka - Broker fails because all log dirs have failed

Question

I am attempting a simple kafka config on Windows os. My zookeeper and kafka installations use default configs (except for data and log dir paths). I can start kafka and produce/consume messages without issue; however, when the broker attempts to delete old messages (I set log retention to 100 ms), I get the following error:

This seems to be this issue: https://issues.apache.org/jira/browse/KAFKA-6188

kafka version: kafka_2.11-1.1.0 Windows 10 Zookeeper version: 3.4.12

I have a few questions:

1. Has anyone seen this issue and is there a workaround?
2. Is running a kafka broker on Windows a viable options at this point? I know it is not supported for Windows and there seem to be multiple critical issues.

Thanks

Answer 1

step 1 : point to a new log directory in server.properties file and save the file

log.dirs=C:\Tools\kafka_2.11-2.1.0\kafka-test-logs

step 2 : start the kafka server again

/bin/windows/kafka-server-start.bat /config/server.properties

Answer 2

I had the same kafka behavior but simply renaming or cleaning log directories wouldn't do the trick. And every time I tried to start kakfa it would crash (it was generating back all the logs deleted).

Solution:

1. Delete the logs as before.
2. Go to ZooKeeper data dir (you find it in \conf\zoo.cfg) and clean it. Restart everything and it should be completely reset.
