kafka玩坏了，如何解决，删除，bug

2.确保所有的生产者，消费者都已经停掉

3.执行bin/kafka-topics.sh --delete --zookeeper localhost:2181 --topic demo

4.执行bin/kafka-topics.sh --list --zookeeper localhost:2181

第二种方式：手工删除

1.在server.properties文件中配置的logs.dir路径中执行rm -rf demo*,将文件全部删除

2.在zookeeper中客户端中,使用./zkCli.sh

[zk: localhost:2181(CONNECTED) 0] ls /brokers/topics
[__consumer_offsets, demo, test]
[zk: localhost:2181(CONNECTED) 1] rmr /brokers/topics/demo
The command ‘rmr’ has been deprecated. Please use ‘deleteall’ instead.
[zk: localhost:2181(CONNECTED) 2] deleteall /brokers/topics/demo
Node does not exist: /brokers/topics/demo
[zk: localhost:2181(CONNECTED) 3] ls /admin/delete_topics/demo
Node does not exist: /admin/delete_topics/dem
