Я использую подключение Kafka для сохранения данных от брокера Kafka для эластичного поиска с помощью платформы Confluent.
Я написал SinkConnector для сохранения данных в эластичном поиске.
Конфигурация Connect-avro-standalone.properties:
key.converter=org.apache.kafka.connect.json.JsonConverter
value.converter=org.apache.kafka.connect.json.JsonConverter
Но когда я отправляю действительный json от производителя avro на Kafka, это приводит к исключению ниже.
