一部の投稿では、トピックの作成が無効になっているためとありますが、私の場合はそうではありません。ストレージトピックはまだ作成されています。
他の人はそれがバージョンの不一致だと述べていますが、それも私の場合ではありません。 kafkaブローカーのバージョンは1.0.0で、Kafka-Connectは次のpom.xmlと同じです。これらの構成はKafka-Connectの開始時に提供されます

これらの警告を修正するために確認する必要があるものは何ですか?データがKafka-Connect経由で配信されているのを確認できますが、これらの警告についてはまだ心配です
これらは単なるWARN
ingsであり、無視してかまいません。将来のリリースでは、それらは正しく抑制されます: https://github.com/Apache/kafka/pull/5876
