我使用Eclipse - > New Scala Project在scala中编写了一个简单的应用程序。使用spark-submit提交Spark Scala作业时出错使用spark-submit
我正在使用Scala 2.10.6和Spark 2.0.2。该应用程序正在编译没有错误，我也导出了jar文件。
我使用下面的命令来执行JAR
spark-submit TowerTest.jar --class com.IFTL.EDI.LocateTower MobLocationData Output1
Scala的代码片段如下
package com.IFTL.EDI
import scala.math.pow
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
object LocateTower {
def main(args: Array[String]){
//create Spark context with Spark configuration
val sc = new SparkContext(new SparkConf().setAppName("TowerCount"))
//helper to add locations function used as a helper in finding tower
centroid
def addLocations(p1: (Double,Double), p2: (Double,Double)) ={
(p1._1 + p2._1,p1._2 + p2._2)
}
}
这不是完整的代码。当我运行这个时，我得到以下错误。
[[email protected] ~]$ spark-submit --class com.IFTL.EDI.LocateTower
TowerTest.jar MobLocationData LocationOut1

我是新来的火花和斯卡拉，所以不知道我错过了什么。
是包'com.IFTL.EDI'内部类？ – philantrovert
是的，它是..我忘记标记第一行（包com.IFTL.EDI）作为代码.. – SuSri
