Я использую SLA-функцию Oozie. Я пытаюсь использовать $ {ordin: nominalTime ()} для номинального времени. Но он выдает ошибку, когда я планирую рабочий процесс.
E0803 : E0803: IO error, E1004: Expression language evaluation error, Validation error :No function is mapped to the name \"coord:nominalTime\"",
