Spark Idea Maven 开发环境搭建

liuming794

　　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，

　　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>

</dependency>
<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

　　6、如果出现以下错误

　　就使用WinRAR打开jar包， 删除META-INF目录下的除了mainfest.mf，.rsa及maven目录以外的其他所有文件
