leader:none question
Hi All
I encountered an error. I delete a certain topic and recreate it , but when I run the shell "kafka-list-topic.sh ", the topic of all partitions
"leader:none".
I have no idea! Please tell me what happened.
Thanks.

Yes, this will be included in either 0.8.1 or 0.8.2.
Thanks,

We forgot to delete that script from the 0.8 beta distro. Since we don't have a way to delete the topic, the cleanest way to come out of this would be to wipe out the cluster and start fresh. If that's too much overhead, you can try bringing the cluster down, deleting the /brokers/topics/<topic> data from zookeeper, delete the local directory from the brokers and restart the cluster. But we haven't tried the latter approach, so not sure if it works.

Hi, Neha !
I use kafka0.8 that offered to delete the function of the topic.
It can delete the topic by running the shell script "bin/kafka-delete-topic.sh "
and create the topic by running the script "kafka-create-topic.sh ".
Now, how do I fix this error to the topic of leader isn't "leader :none"
Thanks.

There is no way to delete topics in Kafka yet. So trying to delete topics
like this might cause failures and cause the topics to be in a bad state.

Hi, Neha !
I use kafka0.8 that offered to delete the function of the topic.
It can delete the topic by running the shell script "bin/kafka-delete-topic.sh "
and create the topic by running the script "kafka-create-topic.sh ".
Now, how do I fix this error to the topic of leader isn't "leader :none"
Thanks.
