iam在運行下面的代碼時得到上述錯誤我觀察到有一些可序列化的問題,但我cudn't完全追蹤。任何一個解釋我能在這裏做的。在此先感謝。異常在線程「主」org.apache.spark.SparkException:任務不可序列化「

enter code here 



    def checkforType(json:String):String={ 
      val parsedjson = parse(json) 
       val res=(parsedjson \\ "Head" \\ "Type").extract[String] 
       (res)  
      } 
    val dstream = KafkaUtils.createStream(ssc, zkQuorum, group, Map("topic" -> 1)).map(_._2) 
      val pType = dstream.map(checkforType) 
      pType.map(rdd => { 
      val pkt= rdd.toString() 
      if(pkt.equals("P300")) { 

      val t300=dstream.map(par300) 
      t300.print() 
     }else if(pkt.equals("P30")) { 
      val t30=dstream.map(par30) 
      t30.print()   
     }else if(pkt.equals("P6")) { 
      val t6=dstream.map(par6) 
      t6.print()   
     } 
     })
