不多说，直接上干货！
IntelliJ IDEA号称当前Java开发效率最高的IDE工具。IntelliJ IDEA有两个版本：社区版(Community)和旗舰版(Ultimate)。社区版时免费的、开源的，但功能较少，旗舰版提供了较多的功能，是收费的，可以试用30天。
强烈推荐，新手刚入门，可以去用社区版，但是，立马还是用旗舰版，我可是走了弯路，当然，体会到其中的棘手还是很不错！
IDEA Community（社区版）再谈之无奈之下还是去安装社区版
IntelliJ IDEA（Community版本）的下载、安装和WordCount的初步使用（本地模式和集群模式）
1、IntelliJ IDEA（Ultimate）的下载
2、IntelliJ IDEA（Ultimate）的安装
3、IntelliJ IDEA（Ultimate）中的scala插件安装
4、用SBT方式来创建工程 或 选择Scala方式来创建工程
5、本地模式或集群模式
我们知道，对于开发而言，IDE是有很多个选择的版本。如我们大部分人经常用的是如下。
Eclipse *版本
Eclipse *下载
而我们知道，对于spark的scala开发啊，有为其专门设计的eclipse，Scala IDE for Eclipse
Scala IDE for Eclipse的下载、安装和WordCount的初步使用（本地模式和集群模式）
这里，我们知道，spark的开发可以通过IntelliJ IDEA或者Scala IDE for Eclipse，包括来构建spark开发环境和源码阅读环境。由于IntelliJ IDEA对scala的支持更好，所以目前spark开发团队使用IntelliJ IDEA作为开发环境。强烈推荐！
1、IntelliJ IDEA（Ultimate）的下载
下载链接： http://www.jetbrains.com/idea/download/
一般，我们使用选择免费的社区版就好了，不过Apache的贡献者可以免费获得商业发行版的使用权。但是，在本博文里，我就是要大家安装Ultimate版本，因为，我有办法教大家成功破解并长期使用。
直接下载最新版本（当然，你也可以下载历史版本）
注意：下载IntelliJ IDEA Ultimate的历史版本
我们找历史版本，Windows7下安装IntelliJ IDEA UltimateEdition 2016.1.4(64)。
2、IntelliJ IDEA（Ultimate）的安装
D:SoftWareIntelliJ IDEAIntelliJ IDEA Ultimate Edition 2016.1.4
创建桌面快捷方式，我只选一个64位的够了；
注意：如果你的JDK是32位的，Tomcat是32位的，估计要使用32位的才行；
创建扩展名关联：都选上吧 ；
安装到这里就完成了，但接下来还有一些步骤需要配置
3、IntelliJ IDEA（Ultimate）的使用
在这之前，先在本地里安装好java和scala
这个必须要同意，不然的话我们安装它干嘛！

为了更加保险，请移步，
IntelliJ IDEA官网：https://www.jetbrains.com
即可，得到。
其实啊，这里永久有效就是。
当然也许这里，以后也会失效，自己从网上搜索就好了，很多很多。
主题皮肤设置，看你喜欢哪一种吧！（当然后期，可以自己更改）
IntelliJ IDEA的黑白色背景切换（Ultimate和Community版本皆通用）
可以根据你的需要调整定制需要的特性：
这里可以安装Scala和IdeaVim支持，但我试了几次，根本安装不上；（其实啊，这里可以安装的上，当然，有时候会安装不上）
果然，IntelliJ IDEA（Ultimate版本）比IntelliJ IDEA（Community版本）多了好多功能啊！
由此可以看到，至2018年01月30日
先选择Create New Project 创建一个空项目看看吧
补安装scala插件（其实就是把它给调出来啦）
这里，以Maven方式，创建一个项目。
如何在Maven官网下载历史版本
Eclipse下Maven新建项目、自动打依赖jar包（包含普通项目和Web项目）
最后，这是我的本地maven的配置文件
别急，等待一会
点击 Got it!
即，在以上过程中，模仿JDK1.8.x和scala2.10.4。
但是，要说么的是，因为，我的本地是scala2.10.4，它默认是2.7.0
为了引起，不必要的麻烦，将自带的删除吧！

本地模式和集群模式的代码，这里我不多赘述。
（1）本地运行
编写完Scala程序后，可以直接在IntelliJ IDEA中以本地(local)模式运行。
在IntelliJ IDEA中，点击Run 按钮，具体见如下
