When the realtime node starts up, it should log, what kind of jar’s it puts into the classpath. You might want to check, if the kafka libraries were downloaded and added to the classpath. In the past i also have had problems with incomplete downloaded Jars. So i cleaned up my local ~/.m2/repository and let druid re-download the dependencies.
