Я хочу сохранить данные из Kafka в корзину s3 с помощью Kafka Connect.У меня уже была запущена тема Кафки, и я создал ведро s3.В моей теме есть данные о Protobuffer, я пробовал с https://github.com/qubole/streamx и получил следующую ошибку:

Я сделал следующие шаги:
- Я клонировалрепозиторий.
mvn DskipTests package
nano config/connect-standalone.properties

Хотелось бы узнать, нормально ли это, или другой способ сохранить данные в S3 от Кафки.
