(отправка от имени клиента Snowflake ...)
.........................
Я пытаюсь подключить Kafka к снежинке, используя Snowflake Connector для Kafka.
Ссылаясь на этот документ: https://docs.snowflake.net/manuals/user-guide/kafka-connector.html
Когда я запускаю Kafka, он инициализирует подключаемые модули Snowflake.
Например:
[2019-08-31 21:52:09,448] INFO Added aliases 'SnowflakeSinkConnector' and 'SnowflakeSink' to plugin 'com.snowflake.kafka.connector.SnowflakeSinkConnector' (org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader:396)

Но после этого он не может прочитать другие атрибуты конфигурации работника.

Я понимаю, что это предупреждения, но после этого мыполучать неудачи. Таким образом, я предполагаю, что это происходит сбой, поскольку он не может инициализировать вышеуказанные значения конфигурации.

Я понимаю, что это может быть проблема конфигурации в том, что в более новой версии Kafka, конфигурация для "topic"был обновлен до «тем», но есть ли другие / дополнительные объяснения, корректирующие действия или рекомендуемые обходные пути?
Спасибо!
