Vahid Hashemian commented on KAFKA-4795: ---------------------------------------- [~omkreddy] Thanks for your comment. I had looked at the JIRA you mentioned when I opened this ticket. I'm still not clear about what the expected behavior is because the inconsistency I explained above currently exists. As I mentioned it is as if there is no intermediary "marked for deletion" step anymore. Either {{\-\-delete}} has no effect at all, or it immediately removes the topic. Even if that is the intended behavior the output statements from {{\-\-delete}} are misleading. > 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 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). -- This message was sent by Atlassian JIRA (v6.3.15#6346)
