在 GKE 升级期间，Strimzi Kafka“没有匹配侦听器的经纪人”

Question

I deployed Kafka using the strimzi operator version 0.15 on GKE and is working fine. The config is this:

  kafka:
    version: 2.3.1
    replicas: 3
    config:
      offsets.topic.replication.factor: 3
      transaction.state.log.replication.factor: 3
      transaction.state.log.min.isr: 2
      log.message.format.version: "2.3"

When I did an upgrade of the kubernetes cluster, obviously also each Kafka Pod has been restarted, and during the upgrade I saw many of the following messages in the logs coming from clients trying to communicate with Kafka:

xxx Partitions have leader brokers without a matching listener, including....

and

Connection to node 1 (kafka-1.redacted.svc.cluster.local/redacted:9092) could not be established. Broker may not be available.

So, I wonder if this is a normal behavior or if this isn't supposed to happen. After the GKE Upgrade everything was working fine without any problem.

During the upgrade also the kafka-exporter (gets deployed together with the strimzi operator) was logging:

In the middle of a leadership election, there is currently no leader for this partition and hence it is unavailable for writes

Thanks for your help
