Kafka topic no longer exists after restart

Question

I created a topic in my local kafka cluster with 3 servers / brokers by running the following from my kafka installation directory

bin/kafka-topics.sh --create         


        

Answer 1

It doesn't mean if you have the broker directories on temp that you had data on it, brokers tends to create these directories if they doesn't exist.

• Could you try to recreate the topic, restart the machine then have a look on the /tmp directory before starting Kafka ?
• Could you try to reproduce with changing the data directory to something other than /tmp ?
