/ 25 марта 2019

Я использую spark 2.4.0, используя python. и прочитайте данные из kafka_2.11-2.0.0 (бинарный не исходный). Я использую spark-submit --jars sspark-streaming-kafka-0-8-assembly_2.11-2.4.0.jar script.py в отчете об ошибке появляется сообщение об ошибке, если кто-то может помочь, спасибо 1001 *
