我已发出删除主题的命令:

I have issued the command to delete a topic:

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

似乎给出了一个快乐的回应:

It seemed to give a happy response:

[2014-05-31 20:58:10,112] INFO zookeeper state changed (SyncConnected) (org.I0Itec.zkclient.ZkClient)
Topic "vip_ips_alerts" queued for deletion.

但现在 10 分钟后该主题仍然出现在 --list 命令中:

But now 10 minutes later the topic still appears in the --list command:

./bin/kafka-topics.sh --zookeeper localhost:2181 --list
vip_ips_alerts - marked for deletion

那是什么意思?该主题何时真正被删除?我如何加快这个过程?

So what does that mean? When will the topic be really deleted? How do I expedite this process?

推荐答案

tl;dr 在 config/server 中设置 delete.topic.enable = true.卡夫卡经纪人的属性和...耐心等待.

tl;dr Set delete.topic.enable = true in config/server.properties of Kafka brokers and...be patient.

最新开发版本的 Kafka 0.8.3-SNAPSHOT 会发生这种情况:

It happens with the latest development version of Kafka 0.8.3-SNAPSHOT:

➜  kafka_2.11-0.8.3-SNAPSHOT git:(trunk) ✗ ./bin/kafka-topics.sh --zookeeper localhost:2181 --create --topic my-topic --partitions 2 --replication-factor 1
Created topic "my-topic".

➜  kafka_2.11-0.8.3-SNAPSHOT git:(trunk) ✗ ./bin/kafka-topics.sh --zookeeper localhost:2181 --describe --topic my-topic
Topic:my-topic  PartitionCount:2    ReplicationFactor:1 Configs:
    Topic: my-topic Partition: 0    Leader: 0   Replicas: 0 Isr: 0
    Topic: my-topic Partition: 1    Leader: 0   Replicas: 0 Isr: 0

➜  kafka_2.11-0.8.3-SNAPSHOT git:(trunk) ✗ ./bin/kafka-topics.sh --zookeeper localhost:2181 --delete --topic my-topic
Topic my-topic is marked for deletion.
Note: This will have no impact if delete.topic.enable is not set to true.

➜  kafka_2.11-0.8.3-SNAPSHOT git:(trunk) ✗ ./bin/kafka-topics.sh --zookeeper localhost:2181 --list
➜  kafka_2.11-0.8.3-SNAPSHOT git:(trunk) ✗

关键是在 config/server.properties 中有 delete.topic.enable=true 用于启动 Kafka 代理.

The point is to have delete.topic.enable=true in config/server.properties that you use to start a Kafka broker.

➜  kafka_2.11-0.8.3-SNAPSHOT git:(trunk) ✗ grep delete.topic.enable config/server.properties
delete.topic.enable=true

您还可以确保经纪人日志中的设置为真:

You can also ensure the setting be true in a broker's log:

➜  kafka_2.11-0.8.3-SNAPSHOT git:(trunk) ✗ ./bin/kafka-server-start.sh config/server.properties
[2015-07-24 22:33:26,184] INFO KafkaConfig values:
        ...
        delete.topic.enable = true
