error.log
According to the above error, I analyzed the reasons as follows：
When Kafka does not have a topic to write to and does not allow automatic creation, an error UnknownTopicOrPartition will be reported, but it will be caught by Kafka::Error
https://github.com/fluent/fluent-plugin-kafka/blob/v0.18.1/lib/fluent/plugin/kafka_producer_ext.rb#L254
and finally thrown in rescue Exception => e.
https://github.com/fluent/fluent-plugin-kafka/blob/master/lib/fluent/plugin/out_kafka2.rb#L411
This is not an ideal situation.
So I adjusted the code to handle the above situation and avoid repeated retries.
