我正在经历一个问题，即我的工作在调用一个类的特定阶段失败了。
这是
行val stockDataFilteredRDD: RDD[stockPriceInfo] =
lineMapToStockPriceInfoObjectRDD
.map(new stockDataFilter(_).requirementsMet.get)
这是我看到的

调用了这个类
class stockDataFilter(val s:stockPriceInfo){
val dateDelim="-"
val timeDelim=":"
val dateAndTime=s.dateTime
val splitDateTime=dateAndTime.split("@")
val dateStamp=splitDateTime(0)
val time=splitDateTime(1)
val splitDate=dateStamp.split(dateDelim)
val splitTime=time.split(timeDelim)
val year=splitDate(0);
val month=splitDate(1);
val day=splitDate(2)
val hour=splitTime(0);
val minute=splitTime(1);
val second=splitTime(2)
val openingBell:LocalTime=newLocalTime(9,30)
val closingBell:LocalTime=newLocalTime(16,0)
val currentTime:LocalTime=newLocalTime(hour.toInt,minute.toInt)
//NonTradingSessions
val newYearsDay:Date=newDate(year.toInt-1900,0,1)
val weekends:List[String]=List("Saturday","Sunday")
val date=new Date(year.toInt-1900,month.toInt-1,day.toInt)
val currentDate=new LocalDate(year.toInt-1990,month.toInt-1,day.toInt)
//NewYorkStockExchangeoperatesfrom9:30a.m.to4:00p.m
def isWithinTradingSession:Boolean={
val isAfterOpen:Boolean=currentTime.isAfter(openingBell)
val isBeforeClose:Boolean=currentTime.isBefore(closingBell)
isAfterOpen&&isBeforeClose
}//return Trueifitiswithingtradingtime
def requirementsMet:Option[stockPriceInfo]=isWithinTradingSessionmatch{
case true=>Some(s)
case false=>None
}
}
我可以在此之前显示（存储在HDFS中）任何内容，但是一旦我添加此行，它就会失败。我查看了日志，没有明显的问题。也没有编译时或运行时异常。我已经被选中了几天。您的帮助将不胜感激..问候
