//主类 package hgs.sparkwc import org.apache.spark.SparkContext import org.apache.spark.SparkConf object WordCount { def main(args: Array[String]): Unit = { val conf = new SparkConf().setAppName("WordCount") val context = new SparkContext() context.textFile(args(0),1).flatMap(_.split(" ")).map((_,1)).reduceByKey(_+_).sortBy(_._2).saveAsTextFile(args(1)) context.stop } } //------------------------------------------------------------------------------------------ //以下式pom.xml文件 <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>hgs</groupId> <artifactId>sparkwc</artifactId> <version>1.0.0</version> <packaging>jar</packaging> <name>sparkwc</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.scala-lang</groupId> <artifactId>scala-library</artifactId> <version>2.11.8</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_2.11</artifactId> <version>2.1.0</version> </dependency> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-client</artifactId> <version>2.6.1</version> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-assembly-plugin</artifactId> <version>2.6</version> <configuration> <archive> <manifest> <!-- 我运行这个jar所运行的主类 --> <mainClass>hgs.sparkwc.WordCount</mainClass> </manifest> </archive> <descriptorRefs> <descriptorRef> <!-- 必须是这样写 --> jar-with-dependencies </descriptorRef> </descriptorRefs> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <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>${project.build.directory}/.scala_dependencies</arg> </args> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.18.1</version> <configuration> <useFile>false</useFile> <disableXmlReport>true</disableXmlReport> <!-- If you have classpath issue like NoDefClassError,... --> <!-- useManifestOnlyJar>false</useManifestOnlyJar --> <includes> <include>**/*Test.*</include> <include>**/*Suite.*</include> </includes> </configuration> </plugin> </plugins> </build> </project>
最后在build assembly:assembly的时候出现以下问题 scalac error: bad option: '-make:transitive' 原因是scala-maven-plugin 插件的配置 <arg>-make:transitive</arg> 有问题,把该行注释掉即可 网上的答案: 删除<arg>-make:transitive</arg> 或者添加该依赖: <dependency> <groupId>org.specs2</groupId> <artifactId>specs2-junit_${scala.compat.version}</artifactId> <version>2.4.16</version> <scope>test</scope> </dependency> 最后在服务器提交任务: ./spark-submit --master spark://bigdata00:7077 --executor-memory 512M --total-executor-cores 3 /home/sparkwc.jar hdfs://bigdata00:9000/words hdfs://bigdata00:9000/wordsout2
