spark 编写规范及技巧

1.为了凸显规范及逼格，使用入口类。

object EntranceA {
  def main(args:Array[String]): Unit ={
    args.toList match {
      case task :: a => task match {
//        case "temprise" => TempRise(a.toArray)
//        case "volt_temp_diff" => VTdiff(a.toArray)
//        case "nocurrent" => NoCurrent(a.toArray)
//        case "batteryact" => BatteryActive(a.toArray)
//        case "historydistance" => HistoryDistance(a.toArray)
//        case "absolutehistorydistance" => HistoryDistance(a.toArray)
//        case "tempchange" => TempChange(a.toArray)
//        case "tempchange2" => TempChange2(a.toArray)
//        case "coolcharge" => CoolCharge(a.toArray)
//        case "tempdraw" => TempDrawData(a.toArray)
        case "geo" => ChargeGeoInfo(a.toArray)
        case "daily" => DailyStatA(a.toArray)
        case "tempchange3" => TempChange3(a.toArray)
        case "temprise2" => TempRise2(a.toArray)
        case _ => print("Invalid task")
      }
      case Nil => print("no args!")
    }
  }

}
