nohup bin/kafka-server-start.sh config/server.properties &
2. Create topic test with 2 partitions
bin/kafka-topics.sh --create --zookeeper localhost:2181 --topic test
--partitions 2 --replication-factor 1
3. Produce some data to topic test
bin/kafka-producer-perf-test.sh --topic test --num-records 50000000
--record-size 100 --throughput=-1 --producer-props
bootstrap.servers=localhost:9092
4. Kill zookeeper and kafka. ProducerPerformance is still running.

5. Remove Zookeeper and Kafka data
rm -rf /tmp/zookeeper/
rm -rf /tmp/kafka-logs/
6. Start zookeeper and kafka
nohup bin/zookeeper-server-start.sh config/zookeeper.properties &
nohup bin/kafka-server-start.sh config/server.properties &
