При выполнении экспресс-обновления с HDF 3.1.0 до 3.3.0 в Ambari 2.7.3, Nifi не удается перезапустить с помощью приведенного ниже журнала. Даже после понижения обновления до 3.1.0 Nifi все равно не может перезапуститься с той же ошибкой. Ниже приведена ошибка во время установки. Пожалуйста, дайте мне знать, как решить эту проблему. Ваша помощь высоко ценится
