Я попытался сделать скрипт для ввода данных из MongoDB в корзину S3:
val mongoDF = spark.read.mongo(readConfig)
mongoDF.repartition(1).write.json(path.format(TABLE))
и этот другой способ тоже
val mongoDF = spark.read.mongo(readConfig)
val mongo_table = mongoDF.sqlContext.sql("""SELECT *FROM mongo_%s""".format(TABLE)).toDF()
mongo_table.repartition(1).write.json(path.format(TABLE))
Итак, я простохочу преобразовать myDF в документ JSON для ввода в мое ведро. Я сею DF. Преобразование, чтобы помочь мне бросить нулевые типы, но я не знаю, решит ли это мою проблему. Можешь мне помочь? У меня была эта ошибка:
