Я скачал Confluent-7.0.0 для локальной машины, установил его. Попытался следовать руководству по быстрому запуску, я набрал «Запуск локальных служб слияния» и получил сообщение об ошибке «Ошибка: не удалось запустить подключение» Не уверен, что пошло не так, это происходит каждый раз, даже со старыми версиями. Я использую виртуальную машину ubuntu.

 Using CONFLUENT_CURRENT: /tmp/confluent.587467 Starting ZooKeeper ZooKeeper is [UP] Starting Kafka Kafka is [UP] Starting Schema Registry Schema Registry is [UP] Starting Kafka REST Kafka REST is [UP] Starting Connect Error: Connect failed to start  

Когда я запустил kafka connect напрямую, он смог запустить службу, но появилось несколько сообщений об ошибках.
