kafka delete topic

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

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

For any given topic what you can do is

1. Stop kafka
2. 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
3. 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
