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

Same happens to me by the end of this tutorial if I follow it without any deviation: [https://data-flair.training/blogs/kafka-cluster/] . It goes away when I restart the nodes. Using in my case \{{kafka_2.11-2.0.0.tgz}} for the three nodes.
