[jira] [Commented] (KAFKA-2937) Topics marked for delete in Zookeeper may become undeletable

["Mayuresh Gharat (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-2937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15064365#comment-15064365 ] 

Mayuresh Gharat commented on KAFKA-2937:
----------------------------------------

I ran a test with few commits behind trunk HEAD : 

1) Started the kafka cluster.
2) Produced data to topic T for quite some time so that enough data is accumulated on kafka brokers.
3) Delete a topic and immediately shutdown the cluster.
4) I could see the topic T under /admin/delete_topics.
5) After I restarted the cluster, the topic T was deleted.

> In our clusters, we occasionally see topics marked for delete, but never actually deleted. It may be due to brokers being restarted while tests were running, but further restarts of Kafka dont fix the problem. The topics remain marked for delete in Zookeeper.
