Это то, что я делаю, чтобы изменить в формате данных 

val df2resultTimestamp = finalXmlDf.withColumn("FilingDateTime_1", date_format(col("FilingDateTime_1"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
      .withColumn("StatementDate_1", date_format(col("StatementDate_1"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
      .withColumn("CapitalChangeAdjustmentDate_1", date_format(col("CapitalChangeAdjustmentDate_1"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
      .withColumn("CumulativeAdjustmentFactor_1", regexp_replace(format_number($"CumulativeAdjustmentFactor_1".cast(DoubleType), 5), ",", ""))

Это вывод, который я получаю, когда FilingDateTime_1 значение столбца изменяется

Значение должно быть 1984-02-14T03:00:00Z

Я не знаю, чего мне здесь не хватает ..

Все, что вам нужно, это дополнительная to_timestamp встроенная функция, как показано ниже 

val df2resultTimestamp = df.withColumn("FilingDateTime_1", date_format(to_timestamp(col("FilingDateTime_1"), "yyyy-MM-dd'T'HH:mm:ss"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
  .withColumn("StatementDate_1", date_format(to_timestamp(col("StatementDate_1"), "yyyy-MM-dd'T'HH:mm:ss"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
  .withColumn("CapitalChangeAdjustmentDate_1", date_format(to_timestamp(col("CapitalChangeAdjustmentDate_1"), "yyyy-MM-dd'T'HH:mm:ss"), "yyyy-MM-dd'T'HH:mm:ss'Z'"))
  .withColumn("CumulativeAdjustmentFactor_1", regexp_replace(format_number($"CumulativeAdjustmentFactor_1".cast(DoubleType), 5), ",", ""))

, который должен дать вам правильный вывод как
