./kafka-run-class.sh kafka.admin.DeleteTopicCommand --topic testKJ1 --zookeeper 127.0.0.1:2181 
./kafka-topics.sh -- zookeeper localhost:2181 --delete --topic testKJ1 
topic delete
(1) delete the topic related files in the log directory

(2) delete the data in zookeeper
Log zookeeper client:
cd $
ZOOKEEPER_HOME bin/zkCli.sh

Delete ls /config/topics/topicname and ls /brokers/topics/topicname
The above two steps will be completely deleted
