> We are running Confluent Platform 7.9 which should be based on Apache Kafka
> 3.9, but this Exception should only be present in Kafka 4.0 from
> https://issues.apache.org/jira/browse/KAFKA-16379
> I will create a ticket with Confluent, but as this code is part of Apache
> Kafka itself it could probably affect others too.
> If I understand the exception the HighWatermarkUpdate operation itself was
> successful but the problem is caused by writing the metrics.
> After a restart of the cluster and the client the problem was resolved, but
> it didn't show up right after the last update or changes.
