Kafka brokers hang when one of broker node killed in cluster and remaining broker nodes are not consuming the data. Below message is getting in the console consumer screen:
WARN Auto offset commit failed for group console-consumer-26249: Offset commit failed with a retriable exception. You should retry committing offsets. (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)
if bring it back stopped service and then all brokers are starting consuming data.
