Я настроил новую систему, spark 2.3.0, python 3.6.0, чтение данных и другие операции, работающие как ожидалось.
Но сбор RDD не выполняется -
distFile = spark.sparkContext.textFile("/Users/aakash/Documents/Final_HOME_ORIGINAL/Downloads/PreloadedDataset/breast-cancer-wisconsin.csv")
distFile.collect()
Ошибка:
py4j.protocol.Py4JJavaError: Произошла ошибка при вызове

Я следовал этому решению для аналогичной проблемы, ( ОШИБКА ПРИ РАБОТЕ с collect () в PYSPARK ) установил последнюю версию Java, но все еще бесполезен.
Что делать?
