idea開發spark環境搭建 以及第一個wordcount程序

開發環境爲 windows10端 和 centOS6.5端

一：windows端環境設置

1.JAVA環境配置：

下載並安裝javaJDK1.8.0

配置java環境變量：

檢查Java環境配置是否成功

2.安裝scala2.11.12(注意不要安裝最新或最高版本，視你的操作系統的Idea版本，否則會出現版本衝突）

配置Scala環境變量：

檢測scala環境是否配好：

3.安裝MAVEN

配置maven環境變量：

檢測maven環境是否配置好：

4.如是要在本地運行請把在linux端配置的hadoop及spark相應的版本軟件在windows下配置

二：配置IDEA

1.安裝idea軟件此處所用2.8版本

（1）配置idea的jdk環境

點擊File => Project Structures，點擊SDKs，“+”號，再點擊JDK

     

添加你的jdk路徑，點擊Apply

（2）配置idea的scala環境

三：開發第一個wordcount程序

1.新建maven工程

將Create from archetype勾上，選擇org.scala.tools.archetypes，選擇完後點擊next：

填寫你的項目信息，點擊next：

注意maven庫的選擇，這裏選擇maven3，User setting file和Local repository的路徑最好不要有中文，不要有中文，以下是錯誤示範，後來下載jar包或depends的時候會出現錯誤，要Override，所以一開始設置時最好不要有中文

2.配置pom.xl：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

3.寫一段程序代碼：
