标题虽然说是搭建，实际只是想记录下搭建过程中遇到的两个问题。
首先在本地创建Scala项目。
环境搭建：
- 首先通过IntelliJ IDEA建立Scala项目（前提是已经安装了Scala），New Project -> Maven -> Create from archtype -> org.scala-tools.archetypes-archetype-simple

- 这是需要选择Scala的版本，我使用的是2.11.8
- 编辑pom.xml配置Spark相关配置

如上所示，这里开始使用的Spark版本是2.10（实际上2.11，因为之后发现一些问题）
遇到的错误：
1. 运行程序时报错

在pom文件中加入如下配置即可
<dependency>
<groupId>org.scala-lang.modules</groupId>
<artifactId>scala-xml_2.11</artifactId>
<version>1.0.6</version>
</dependency>
2. 增加上面配置后，错误发生变化

上网查询发现应该是Spark版本和Scala版本冲突，将pom文件Spark版本由2.1.0改为2.1.1
