我在 Windows 10 机器上运行 spark 程序。
我正在尝试运行以下火花程序
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
import org.apache.spark.sql.Column
import org.apache.spark.sql.functions._
import org.apache.spark.sql.SQLContext
import org.apache.spark.sql._
import org.apache.spark.sql.SQLImplicits
import org.apache.spark.sql.expressions.Window
import org.apache.spark.sql.TypedColumn
import org.apache.spark.sql.Encoder
import org.apache.spark.sql.Encoders
import com.databricks.spark.csv
object json1 {
def main(args : Array[String]){
val conf = new SparkConf().setAppName("Simple Application").setMaster("local[2]").set("spark.executor.memory", "1g")
val sc = new org.apache.spark.SparkContext(conf)
val sqlc = new org.apache.spark.sql.SQLContext(sc)
val NyseDF = sqlc.load("com.databricks.spark.csv",Map("path" -> args(0),"header"->"true"))
NyseDF.registerTempTable("NYSE")
NyseDF.printSchema()
}
}
当我在 eclipse 中通过运行应用程序模式运行程序并传递参数时
作为
src/test/resources/demo.text
它失败并出现以下错误。
