Subject kafka_2.9.2-0.8.2.0 - Topic marked for deletion
Date Tue, 03 Nov 2015 21:15:24 GMT
Hi,

I am trying to delete the kafka topic, verison I am using is 2.9.2-0.8.2. I am using dockerized
kafka to delete the topic already created and didn’t set the “delete.topic.enable=true”.
 When I am listing the topics, it is giving as “<TOPIC> marked for deletion”.

Is this a bug? However when I am setting “delete.topic.enable=true” as true, it gets deleted
immediately. Apart from this I have one more question, once the topic is marked for deletion;
will messages be still available for consumer?

I do see regular updated in controller update with

[2015-11-03 21:05:57,753] TRACE [Controller 1]: checking need to trigger partition rebalance
(kafka.controller.KafkaController)

[2015-11-03 21:05:57,754] DEBUG [Controller 1]: preferred replicas by broker Map(1 -> Map([abcdefghApp,0]
-> List(1), [abcdefgApp,0] -> List(1), [abcdefApp,0] -> List(1), [adbceApp,0] ->
List(1), [abcdApp,0] -> List(1), [abcApp,0] -> List(1), [abApp,0] -> List(1), [aApp,0]
-> List(1))) (kafka.controller.KafkaController)

[2015-11-03 21:05:57,754] DEBUG [Controller 1]: topics not in preferred replica Map() (kafka.controller.KafkaController)

[2015-11-03 21:05:57,754] TRACE [Controller 1]: leader imbalance ratio for broker 1 is 0.000000
(kafka.controller.KafkaController)

Out of these aApp,abApp and abcApp topics has been marked for deletion.

Thanks,
Avinash
