Когда я пытаюсь запустить Kafka connect для реактора эластичного поиска, в автономном режиме я получаю следующую ошибку:
Exception in thread "main" org.apache.kafka.common.config.ConfigException: Missing required configuration "key.converter" which has no default value.
at org.apache.kafka.common.config.ConfigDef.parseValue(ConfigDef.java:463)

Могу я решить эту ошибку?
РЕДАКТИРОВАТЬ 01/05/2018 Извините, я стараюсь быть более конкретным. Я использую соединитель потокового реактора: https://github.com/Landoop/stream-reactor Это команда, которую я запускаю из экземпляра EC2, в котором есть уникальный брокер моей кафки:
./bin/connect-standalone.sh config/elastic-config.properties config/connect-
standalone.properties.
