----------------------------------------
[~ijuma] [~hachikuji] I'd appreciate your clarification on this JIRA.
> Confusion around topic deletion
> -------------------------------
>
> Key: KAFKA-4795
> URL: https://issues.apache.org/jira/browse/KAFKA-4795
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.10.2.0
> Reporter: Vahid Hashemian
> Assignee: Vahid Hashemian
>
> The topic deletion works like this in 0.10.2.0:
> # {{bin/zookeeper-server-start.sh config/zookeeper.properties}}
> # {{bin/kafka-server-start.sh config/server.properties}} (uses default
> {{server.properties}})
> # {{bin/kafka-topics.sh --zookeeper localhost:2181 --create --topic test
> --replication-factor 1 --partitions 1}} (creates the topic {{test}})
> # {{bin/kafka-topics.sh --zookeeper localhost:2181 --list}} (returns {{test}})
> # {{bin/kafka-topics.sh --zookeeper localhost:2181 --delete --topic test}}
> (reports {{Topic test is marked for deletion. Note: This will have no impact
> if delete.topic.enable is not set to true.}})
> # {{bin/kafka-topics.sh --zookeeper localhost:2181 --list}} (returns {{test}})
> Previously, the last command above returned {{test - marked for deletion}},
> which matched the output statement of the {{--delete}} topic command.
> Continuing with the above scenario,
> # stop the broker
> # add the broker config {{delete.topic.enable=true}} in the config file
> # {{bin/kafka-server-start.sh config/server.properties}} (this does not
> remove the topic {{test}}, as if the topic was never marked for deletion).
> # {{bin/kafka-topics.sh --zookeeper localhost:2181 --delete --topic test}}
> (reports {{Topic test is marked for deletion. Note: This will have no impact
> if delete.topic.enable is not set to true.}})
> # {{bin/kafka-topics.sh --zookeeper localhost:2181 --list}} (returns no
> topics).
> It seems that the "marked for deletion" state for topics no longer exists.
> I opened this JIRA so I can get a confirmation on the expected topic deletion
> behavior, because in any case, I think the user experience could be improved
> (either there is a bug in the code, or the command's output statement is
> misleading).
