1.配置Maven
1）打开IDEA：File–>Settings,

*注意Settings.xml文件配置：
仓库地址：<localRepository>D:\software\repository</localRepository>

阿里云镜像：

<mirror>
      <id>alimaven</id>
      <name>aliyun maven</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>        
    </mirror>

JDK配置：

<profile>  
		  <id>jdk-1.8</id>  
		   <activation>  
		     <activeByDefault>true</activeByDefault>  
		     <jdk>1.8</jdk>  
		   </activation>  
			<properties>  
				<maven.compiler.source>1.8</maven.compiler.source>  
				<maven.compiler.target>1.8</maven.compiler.target>  
				<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
			</properties>
		</profile>

2.新建Maven项目：

项目新建后，打开 pom.xml文件，添加如下依赖：

<dependencies>
<dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-common</artifactId>
            <version>2.8.4</version>
        </dependency>

        <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-common</artifactId>
            <version>2.8.4</version>
        </dependency>
        <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-hdfs</artifactId>
            <version>2.8.4</version>
        </dependency>
        <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-client</artifactId>
            <version>2.8.4</version>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.10</version>
        </dependency>

        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.7</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/junit/junit -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>
   </dependencies>

最后
3.配置Hadoop：
1）将下载的Hadoop压缩包解压，然后配置HADOOP_HOME环境变量即可:

注意：bin目录下必需要有Winutils.exe和hadoop.dll两个文件
