Hi I got a problem when reading a textfile which contains nested complex type data and got a type unmatch problem.Any hint will be appreciated. The problem take place at "map(s => s.map" as "type mismatch; found : scala.collection.immutable.IndexedSeq[Array[com.redhadoop.bean.StructField1]] required: Seq[com.redhadoop.bean.StructField1]" here is my codeļ¼ import sqlContext.createSchemaRDD val ultraComplexTextfile = spark.textFile("/examples/src/main/resources/aggrnew.text").map(_.split("\001")).map(p => UltraComplexTextFileTable( p(0).trim.toInt, p(1).trim.map(_.toString.split("\002")).map(s => s.map(_.toString.split("\003")).map(t => StructField1( t(0).toString.trim.toInt - 48, t(1).toString.trim.toInt - 48, t(2).toString.trim.toInt - 48, t(3).toString.trim.toInt - 48, t(4).toString.trim.toInt - 48, t(5).toString.trim.toFloat - 48, t(6).toString.trim.toFloat - 48, t(7).toString.trim.toFloat - 48 )) ), p(2)) )
and my case class below: case class UltraComplexTextFileTable ( frameid:Int, detaillist:Seq[StructField1], frame:String ) case class StructField1( targetNum:Int, x:Int, y:Int, width:Int, height:Int, HM:Float, HS:Float, HT:Float ) -------------------------------- Thanks&Best regards!
