查看zookeeper的注册信息

　　

/bin/目录下下

sh zkCli.sh

进入客户端目录下：

查看根目录 

[zk: localhost:2181(CONNECTED) 11] ls /
[cluster, controller, brokers, zookeeper, admin, isr_change_notification, log_dir_event_notification, controller_epoch, spark, consumers, latest_producer_id_block, config, hbase]

[zk: localhost:2181(CONNECTED) 10]  ls /brokers       
[ids, topics, seqid]

[zk: localhost:2181(CONNECTED) 12] ls /brokers/ids
[3, 4]

[zk: localhost:2181(CONNECTED) 13] ls /brokers/topics
[tenth, topic_xxx, MMMM, test, tenth111, topic_start, xxxxx, second, calllog, yyyy, zzzz, topic_event, first, __consumer_offsets]

在zk上删除kafka的 topics

[zk: localhost:2181(CONNECTED) 2] rmr /brokers/topics
[zk: localhost:2181(CONNECTED) 3] ls /brokers
[ids, seqid]
[zk: localhost:2181(CONNECTED) 4] ls /brokers/topics
Node does not exist: /brokers/topics

删除某一个topic 两步骤

第一步：：

[zk: localhost:2181(CONNECTED) 0] ls /brokers/topics
[topic_event, __consumer_offsets, topic_start]
[zk: localhost:2181(CONNECTED) 1] del

delquota   delete
[zk: localhost:2181(CONNECTED) 1] delete /brokers/topics/

topic_event          __consumer_offsets   topic_start
[zk: localhost:2181(CONNECTED) 1] delete /brokers/topics/topic_

topic_event   topic_start
[zk: localhost:2181(CONNECTED) 1] delete /brokers/topics/topic_start
[zk: localhost:2181(CONNECTED) 2] ls /brokers/topics
[topic_event, __consumer_offsets]
[zk: localhost:2181(CONNECTED) 3]

第二步骤：：：

把 topic文件也要删除掉

[root@hadoop104 logs]# rm -rf topic_start-0/
[root@hadoop104 logs]# pwd
/opt/module/kafka_2.11-1.0.0/logs
[root@hadoop104 logs]#
