eclipse安装scala和spark编译环境并上传到集群运行

本地环境：Window+eclipse4.3.2+scala.2.10.5+JDK1.7

1.scala安装，JDK安装简单，请自查

2.eclipse安装:http://www.eclipse.org/downloads/packages/release/Kepler/SR2

如果安装eclipse 4.5会装不上插件

3.eclipse安装插件

help->install new software

在http://scala-ide.org/download/prev-stable.html中找到http://download.scala-ide.org/sdk/helium/e37/scala210/stable/site输入，然后等待安装，不细讲

提醒：由于网络问题，可能需要install多次，前几次都会失败，多试几次，有时候可能需要五六次。。。

4.安装好后就可以new scala project

5.再导入spark的spark-assembly-1.5.2-hadoop2.6.0.jar

6.本地运行：

// scalastyle:off println
package test1

import scala.math.random

import org.apache.spark._

/** Computes an approximation to pi */
object SparkPi {
def main(args: Array[String]) {
val conf = new SparkConf().setAppName("Spark Pi ").setMaster("local")
val spark = new SparkContext(conf)
val slices = if (args.length > 0) args(0).toInt else 2
println("slices:\n"+slices)
println("args.length:\n"+args.length)
val n = math.min(100000L * slices, Int.MaxValue).toInt // avoid overflow
val count = spark.parallelize(1 until n, slices).map { i =>
val x = random * 2 - 1
val y = random * 2 - 1
if (x*x + y*y < 1) 1 else 0
}.reduce(_ + _)
println("Pi is roughly " + 4.0 * count / n)
spark.stop()
}
}
// scalastyle:on println

运行结果：
