Delete topic in Kafka 0.8.1.1

Question

I need to delete the topic test in Apache Kafka 0.8.1.1.

As expressed in the documentation here, I have executed:

bin/kafka-topics.sh --         


        

Answer 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?

Answer 2

Add below line in ${kafka_home}/config/server.properties

delete.topic.enable=true

Restart the kafka server with new config:

${kafka_home}/bin/kafka-server-start.sh ~/kafka/config/server.properties

Delete the topics you wish to:

${kafka_home}/bin/kafka-topics.sh --delete  --zookeeper localhost:2181  --topic daemon12

Answer 3

First, you run this command to delete your topic:

$ bin/kafka-topics.sh --delete --bootstrap-server localhost:9092 --topic <topic_name>

List active topics to check delete completely:

$ bin/kafka-topics.sh --list --bootstrap-server localhost:9092

Answer 4

As mentioned in doc here

Topic deletion option is disabled by default. To enable it set the server config delete.topic.enable=true Kafka does not currently support reducing the number of partitions for a topic or changing the replication factor.

Make sure delete.topic.enable=true

Answer 5

Step 1: Make sure you are connected to zookeeper and Kafka running

Step 2: To delele the Kafka topic run Kafka-topic (Mac) or Kafka-topic.sh if use (linux/Mac) add the port and --topic with name of your topic and --delete it just delete the topic with success.

# Delete the kafka topic
# it will delete the kafka topic
kafka-topics --zookeeper 127.0.0.1:2181 --topic name_of_topic --delete
# or
kafka-topics.sh --zookeeper 127.0.0.1:2181 --topic name_of_topic --delete

Answer 6

It seems that the deletion command was not officially documented in Kafka 0.8.1.x because of a known bug (https://issues.apache.org/jira/browse/KAFKA-1397).

Nevertheless, the command was still shipped in the code and can be executed as:

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

In the meantime, the bug got fixed and the deletion command is now officially available from Kafka 0.8.2.0 as:

bin/kafka-topics.sh --delete --zookeeper localhost:2181 --topic test
