What Jun described is correct, currently the consumer asynchronously fails rebalance. But you can monitor the consumer to detect when a rebalance operation fails since that will manifest as lag on the consumer. Please see this<https://cwiki.apache.org/confluence/display/KAFKA/FAQ#FAQ-Myconsumerseemstohavestopped,why?>to learn about consumer lag monitoring.
