Я недавно включил SSL и попытался запустить Kafka connect в распределенном режиме.При запуске
connect-distributed connect-distributed.properties
я получаю следующие ошибки:

Я также пытался увеличить max и начальный размер кучиустановив переменную среды KAFKA_HEAP_OPTS , запустив
KAFKA_HEAP_OPTS="-Xms4g -Xmx6g" connect-distributed connect-distributed.properties
, но все равно не работает.
Мои вопросы:
- Может ли проверка подлинности SSL повлиять на использование памяти каким-либо образом?
- Как устранить проблему?
РЕДАКТИРОВАТЬ:
Я попытался отключить SSL, и все работает без проблем.
