Hi, I have a Kafka cluster with 3 nodes.
I pass the nodes in the cluster to a consumer app I am building as bootstrap servers. When one of the nodes in the cluster is down, the consumer group sometimes CAN read records from the server but sometimes CAN NOT. In both cases, the same Kafka node is down. Is this behavior normal? Isn't it enough to only have one of the nodes in the Kafka cluster be up and running? I have not delved much into setup and administration of Kafka clusters, but I thought Kafka uses the nodes for HA and as long as one node is up and running, the cluster remains healthy and working. Best regards, Behrang Saeedzadeh
