1：spark shell仅在测试和验证我们的程序时使用的较多，在生产环境中，通常会在IDE中编制程序，然后打成jar包，然后提交到集群，最常用的是创建一个Maven项目，利用Maven来管理jar包的依赖。
2：配置Maven的pom.xml：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.bie</groupId> <artifactId>sparkWordCount</artifactId> <version>1.0-SNAPSHOT</version> <properties> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> <encoding>UTF-8</encoding> <scala.version>2.10.6</scala.version> <scala.compat.version>2.10</scala.compat.version> </properties> <dependencies> <dependency> <groupId>org.scala-lang</groupId> <artifactId>scala-library</artifactId> <version>${scala.version}</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_2.10</artifactId> <version>1.5.2</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-streaming_2.10</artifactId> <version>1.5.2</version> </dependency> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-client</artifactId> <version>2.6.2</version> </dependency> </dependencies> <build> <sourceDirectory>src/main/scala</sourceDirectory> <testSourceDirectory>src/test/scala</testSourceDirectory> <plugins> <plugin> <groupId>net.alchim31.maven</groupId> <artifactId>scala-maven-plugin</artifactId> <version>3.2.0</version> <executions> <execution> <goals> <goal>compile</goal> <goal>testCompile</goal> </goals> <configuration> <args> <arg>-make:transitive</arg> <arg>-dependencyfile</arg> <arg>${project.build.directory}/.scala_dependencies</arg> </args> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.18.1</version> <configuration> <useFile>false</useFile> <disableXmlReport>true</disableXmlReport> <includes> <include>**/*Test.*</include> <include>**/*Suite.*</include> </includes> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>2.3</version> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <filters> <filter> <artifact>*:*</artifact> <excludes> <exclude>META-INF/*.SF</exclude> <exclude>META-INF/*.DSA</exclude> <exclude>META-INF/*.RSA</exclude> </excludes> </filter> </filters> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <mainClass>com.bie.WordCount</mainClass> </transformer> </transformers> </configuration> </execution> </executions> </plugin> </plugins> </build> </project>
注意：配置好pom.xml以后，点击Enable Auto-Import即可;
3：将src/main/java和src/test/java分别修改成src/main/scala和src/test/scala，与pom.xml中的配置保持一致（）；
4：新建一个scala class，类型为Object，然后编写spark程序，如下所示：
import org.apache.spark.{SparkConf, SparkContext} object WordCount { def main(args: Array[String]): Unit = { //创建SparkConf()并且设置App的名称 val conf = new SparkConf().setAppName("wordCount"); //创建SparkContext,该对象是提交spark app的入口 val sc = new SparkContext(conf); //使用sc创建rdd,并且执行相应的transformation和action sc.textFile(args(0)).flatMap(_.split(" ")).map((_ ,1)).reduceByKey(_ + _,1).sortBy(_._2,false).saveAsTextFile(args(1)); //停止sc，结束该任务 sc.stop(); } }
5：使用Maven打包：首先修改pom.xml中的mainClass，使其和自己的类路径对应起来：
然后，点击idea右侧的Maven Project选项，点击Lifecycle,选择clean和package，然后点击Run Maven Build：
等待编译完成，选择编译成功的jar包，并将该jar上传到Spark集群中的某个节点上：
记得，启动你的hdfs和Spark集群，然后使用spark-submit命令提交Spark应用（注意参数的顺序）：
可以看下简单的几行代码，但是打成的包就将近百兆，都是封装好的啊，感觉牛人太多了。
然后开始进行Spark Submit提交操作，命令如下所示：
[root@master spark-1.6.1-bin-hadoop2.6]# bin/spark-submit > --class com.bie.WordCount > --master spark://master:7077 > --executor-memory 512M > --total-executor-cores 2 > /home/hadoop/data_hadoop/sparkWordCount-1.0-SNAPSHOT.jar > hdfs://master:9000/wordcount.txt > hdfs://master:9000/output
或者如下：
bin/spark-submit --class com.bie.WordCount --master spark://master:7077 --executor-memory 512M --total-executor-cores 2 /home/hadoop/data_hadoop/sparkWordCount-1.0-SNAPSHOT.jar hdfs://master:9000/wordcount.txt hdfs://master:9000/outpu
操作如下所示：
可以在图形化页面看到多了一个Application：
然后呢，就出错了，学知识，不出点错，感觉都不正常：

解决思路，百度了一下，也没缕出思路，就只知道是连接超时了，超过了120s，然后呢，我感觉是自己内存设置小了，因为开的虚拟机，主机8G，三台虚拟机，每台分了1G内存，然后设置Spark可以占用800M，跑程序的时候，第一次设置为512M，就连接超时了，第二次设置为了700M，顺利跑完，可以看看跑的过程，还是很有意思的：
