The /brokers/ids nodes are ephemeral nodes that only exists while the brokers maintain a session to zookeeper. There is more information on Kafka's Zookeeper usage here: - http://kafka.apache.org/documentation.html - look for "Broker Node Registry" - https://cwiki.apache.org/confluence/display/KAFKA/Kafka+data+structures+in+Zookeeper
Hopefully that helps debug your issue.
