kafka delete topic

Don't think it is supported yet. Take a look at this JIRA tracking Delete Topic. For delete manually

Shutdown the cluster
Clean kafka log dir (specified by the log.dir attribute in kafka config file ) as well the zookeeper data
Restart the cluster

For any given topic what you can do is

Stop kafka
Clean kafka log specific to partition, kafka stores its log file in a format of "logDir/topic-partition" so for a topic named "MyTopic" the log for partition id 0 will be stored in /tmp/kafka-logs/MyTopic-0 where /tmp/kafka-logs is specified by the log.dir attribute
Restart kafka

This is NOT a good and recommended approach but it should work. In the Kafka broker config file the log.retention.hours.per.topic attribute is used to define The number of hours to keep a log file before deleting it for some specific topic

bin/kafka-run-class.sh kafka.admin.DeleteTopicCommand --zookeeper localhost:2181 --topic test

命令删除后数据文件依然存在，上边的方法是根本删除

create kafka-delete-topic.sh file
