For example, if you lost the Kafka data in ZooKeeper , the mapping of replicas to Brokers and topic configurations would be lost as well, making your Kafka cluster no longer functional and potentially resulting in. Note that the user may also provide a static JAAS configuration file using the mechanisms described in the Java SE Documentation. The ZooKeeper component allows interaction with a ZooKeeper cluster and exposes the following features to Camel: Creation of nodes in any of the ZooKeeper create modes. Running Kafka also requires running a Zookeeper cluster, which has many of the same challenges as running the Kafka cluster. Join LinkedIn Summary. kafka-zookeeper-nodes.
