When we were in testing phase, we would either create a new topic with the correct details or shut the cluster down and hard kill the topic in zookeeper + local disk. In prod we have the cluster configured via configuration management and auto create turned off.
The ability to delete a topic in a live, running kafka cluster is tricky, and the implementations of it have been subtly incorrect (and therefore dangerous). I know that there is work happening around that, but haven't kept up with the status of it. Maybe in 8.2? It sounds conceptually simpler to implement with the new metadata API. -Mark > On Jun 18, 2014, at 4:06, "Shlomi Hazan" <shl...@viber.com> wrote: > > Hi, > > Doing some evaluation testing, and accidently create a queue with wrong > replication factor. > > Trying to delete as in: > > kafka_2.10-0.8.1.1/bin/kafka-topics.sh --zookeeper localhost:2181 --delete > --topic replicated-topic > > Yeilded: > > Command must include exactly one action: --list, --describe, --create or > -alter > > Event though this page (https://kafka.apache.org/documentation.html) says: > > > > And finally deleting a topic: > >> bin/kafka-topics.sh --zookeeper zk_host:port/chroot --delete --topic > my_topic_name > > WARNING: Delete topic functionality is beta in 0.8.1.
