Topic mobilePhone does not exist on ZK

问题

kafka-topic.sh 查询topic详细信息时，查询结果没有数据或者报错

Error while executing topic command : Topic mobilePhone does not exist on ZK path master:2181,slave1:2181,slave3:2181

分析

造成这个错误的原因也是 在执行命令时，忘记输入配置zookeeper时的根目录hostname:port/kafak，直接写成了主机名加端口号，从而zookeeper找不到topic的路径。

测试

-bash-4.2$ bin/kafka-topics.sh  --topic topic_test1 --zookeeper 192.168.15.11:2181,192.168.15.12:2181,192.168.15.13:2181 --describe

-bash-4.2$ bin/kafka-topics.sh  --topic topic_test1 --zookeeper 192.168.15.11:2181,192.168.15.12:2181,192.168.15.13:2181/testkafka --describe
