eclipse构建maven+scala+spark工程

前提条件

下载安装Scala IDE build of Eclipse SDK

构建工程

1、新建maven工程

2、配置项目信息

3、新建scala对应的Source Folder

4、添加scala对应Archetype

5、配置pom.xml添加依赖包

到此项目部署配置完成。

运行scala程序

编写scala程序

package com.lilei

object test {
  def main(args: Array[String]): Unit = {
    println("hello scala world !")
  }
}

运行本地spark程序

编写spark程序

package com.lilei

import org.apache.spark.SparkConf
import org.apache.spark.SparkContext

object hello_spark {

  def main(args: Array[String]): Unit = {
    val conf = new SparkConf()
      .setAppName("dsfsdf").setMaster("local")

    val sc = new SparkContext(conf)

    val path = "C:\\test\\es\\elasticsearch-5.6.3\\config\\jvm.options"

    sc.textFile(path).foreach(println)
  }

}
