But nothing happens when the node is deleted. running on Kafka the following command bin/kafka-topics.sh --list --zookeeper localhost:2181 I can see that the topic is still there after removing an agent. Workaround: Manually delete the topic in Kafka using bin/kafka-topics.sh --topic jenkinssecure.8081.overtakke-topic --delete --zookeeper localhost:2181 and recreate the node in Jenkins   Add Comment   This message was sent by Atlassian Jira (v7.11.2#711002-sha1:fdc329d) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
