Delete topic in Kafka 0.8.1.1

Deleting topic isn't always working in 0.8.1.1

Deletion should be working in the next release, 0.8.2

kafka-topics.sh --delete --zookeeper localhost:2181 --topic your_topic_name

  Topic your_topic_name is marked for deletion.
  Note: This will have no impact if delete.topic.enable is not set to true.

Is it possible to delete a topic?
