Answer 1

You can not delete a topic when consuming it. Use bin/kafka-consumer-groups.sh or simple ps -aux|grep Consumer to find any possible consumers which block the operation.

Answer 2

remove meta data in zookeeper

./bin/zookeeper-shell.sh localhost:2181
rmr /brokers/topics/mytopic
rmr /admin/delete_topics/mytopic
