一、安装jdk

jdk版本最好是1.7以上，设置好环境变量，安装过程，略。

二、安装Maven

我选择的Maven版本是3.3.3，安装过程，略。

编辑Maven安装目录conf/settings.xml文件，

<!-- 修改Maven 库存放目录-->

<localRepository>D:\maven-repository\repository</localRepository>

三、安装Idea

安装过程，略。

四、创建Spark项目

1、新建一个Spark项目，

2、选择Maven，从模板创建项目，

3、填写项目GroupId等，

4、选择本地安装的Maven和Maven配置文件。

5、next

6、创建完毕，查看新项目结构：

7、自动更新Maven pom文件

8、编译项目

如果出现这种错误，这个错误是由于Junit版本造成的，可以删掉Test，和pom.xml文件中Junit的相关依赖，

即删掉这两个Scala类：

和pom.xml文件中的Junit依赖：

    <dependency>

      <groupId>junit</groupId>

      <artifactId>junit</artifactId>

      <version>4.12</version>

    </dependency>

　9、刷新Maven依赖

10、引入Jdk和Scala开发库

11、在pom.xml加入相关的依赖包，包括Hadoop、Spark等

<dependency>

			<groupId>commons-logging</groupId>

			<artifactId>commons-logging</artifactId>

			<version>1.1.1</version>

			<type>jar</type>

		</dependency>

		<dependency>

			<groupId>org.apache.commons</groupId>

			<artifactId>commons-lang3</artifactId>

			<version>3.1</version>

		</dependency>

		<dependency>

			<groupId>log4j</groupId>

			<artifactId>log4j</artifactId>

			<version>1.2.9</version>

		</dependency>

		<dependency>

			<groupId>junit</groupId>

			<artifactId>junit</artifactId>

			<version>4.12</version>

		</dependency>

		<dependency>

			<groupId>org.apache.hadoop</groupId>

			<artifactId>hadoop-client</artifactId>

			<version>2.7.1</version>

		</dependency>

		<dependency>

			<groupId>org.apache.hadoop</groupId>

			<artifactId>hadoop-common</artifactId>

			<version>2.7.1</version>

		</dependency>

		<dependency>

			<groupId>org.apache.hadoop</groupId>

			<artifactId>hadoop-hdfs</artifactId>

			<version>2.7.1</version>

		</dependency>

		<dependency>

			<groupId>org.apache.spark</groupId>

			<artifactId>spark-core_2.10</artifactId>

			<version>1.5.1</version>

		</dependency>

		<dependency>

			<groupId>org.apache.spark</groupId>

			<artifactId>spark-sql_2.10</artifactId>

			<version>1.5.1</version>

		</dependency>

　　然后刷新maven的依赖，

12、新建一个Scala Object。

测试代码为：

  def main(args: Array[String]) {

    println("Hello World!")

    val sparkConf = new SparkConf().setMaster("local").setAppName("test")

    val sparkContext = new SparkContext(sparkConf)

  }

　　执行，

如果报了以下错误，

java.lang.SecurityException: class "javax.servlet.FilterRegistration"'s signer information does not match signer information of other classes in the same package

	at java.lang.ClassLoader.checkCerts(ClassLoader.java:952)

	at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144)

　　可以把servlet-api 2.5 jar删除即可：

最好的办法是删除pom.xml中相关的依赖，即

    <dependency>

      <groupId>org.apache.hadoop</groupId>

      <artifactId>hadoop-client</artifactId>

      <version>2.7.1</version>

    </dependency>

最后的pom.xml文件的依赖是

<dependencies>

    <dependency>

      <groupId>org.apache.hadoop</groupId>

      <artifactId>hadoop-common</artifactId>

      <version>2.7.1</version>

    </dependency>

    <dependency>

      <groupId>org.apache.hadoop</groupId>

      <artifactId>hadoop-hdfs</artifactId>

    </dependency>

    <dependency>

    </dependency>

    <dependency>

      <artifactId>spark-streaming_2.10</artifactId>

      <version>1.5.2</version>

    </dependency>

  </dependencies>

　　

　　如果是报了这个错误，也没有什么问题，程序依旧可以执行，

　　最后看到的正常输出：

Process finished with exit code 0

　　至此，开发环境搭建完毕。

五、打jar包

1、新建一个Scala Object

代码是：

package com.test

import org.apache.spark.{SparkConf, SparkContext}

/**

  * Created by pc on 2016/9/20.

  */

object WorldCount {

  def main(args: Array[String]) {

    val dataFile = args(0)

    val output = args(1)

    val sparkConf = new SparkConf().setAppName("WorldCount")

    val sparkContext = new SparkContext(sparkConf)

    val lines = sparkContext.textFile(dataFile)

    val counts = lines.flatMap(_.split(",")).map(s => (s,1)).reduceByKey((a,b) => a+b)

    counts.saveAsTextFile(output)

    sparkContext.stop()

  }

}

　

2、  File -》Project Structure

3、点击ok

可以设置jar包输出目录：

4、build Artifact

5、运行：

把测试文件放到HDFS的/test/ 目录下，提交：

spark-submit --class com.test.WorldCount --master spark://192.168.18.151:7077 sparktest.jar /test/data.txt /test/test-01
