-------------------------------

             Summary: /admin/delete_topics is not in the list of zookeeper watchers
                 Key: KAFKA-14234
                 URL: https://issues.apache.org/jira/browse/KAFKA-14234
             Project: Kafka
          Issue Type: Bug
          Components: controller
    Affects Versions: 3.2.1
            Reporter: Yan Xue


I deployed the Kafka cluster on Kuberentes and am trying to figure out how topic deletion works. I know Kafka controller has the topic deletion manager which watches the node change in the zookeeper. Whenever a topic is deleted, the manager is triggered. I expected to see that the {{/admin/delete_topics}} is in the watcher list. However, I didn't find it. Sample output:

root@kafka-broker-2:/opt/kafka# echo wchc | nc ZOOKEEPER_IP 2181
0x200100211390000
