Hi Mark:

If you continue to see these error messages even after all Kafka brokers have started up successfully, then there may be some kind of connectivity issue between between the broker nodes. If these messages do not continue after all Kafka brokers have started, you can safely ignore these messages.

Thank you,

Jeff Groves
