配置 spark-env.sh export JAVA_HOME=/apps/jdk1.8.0_181 export SPARK_MASTER_HOST=bigdata00 export SPARK_MASTER_PORT=7077 slaves bigdata01 bigdata02 bigdata03 启动spark shell ./spark-shell --master spark://bigdata00:7077 --executor-memory 512M 用spark shell 完成一个wordcount scala> sc.textFile("hdfs://bigdata00:9000/words").flatMap(_.split(" ")).map((_,1)).reduceByKey(_+_).collect 结果: res3: Array[(String, Int)] = Array((this,1), (is,4), (girl,3), (love,1), (will,1), (day,1), (boreing,1), (my,1), (miss,2), (test,2), (forget,1), (spark,2), (soon,1), (most,1), (that,1), (a,2), (afternonn,1), (i,3), (might,1), (of,1), (today,2), (good,1), (for,1), (beautiful,1), (time,1), (and,1), (the,5))
//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4.0.0 hgs sparkwc 1.0.0 jar sparkwc http://maven.apache.org UTF-8 org.scala-lang scala-library 2.11.8 org.apache.spark spark-core_2.11 2.1.0 org.apache.hadoop hadoop-client 2.6.1 maven-assembly-plugin 2.6 hgs.sparkwc.WordCount jar-with-dependencies make-assembly package single org.apache.maven.plugins maven-compiler-plugin 1.8 net.alchim31.maven scala-maven-plugin 3.2.0 compile testCompile -dependencyfile ${project.build.directory}/.scala_dependencies org.apache.maven.plugins maven-surefire-plugin 2.18.1 false true **/*Test.* **/*Suite.*
最后在build assembly:assembly的时候出现以下问题 scalac error: bad option: '-make:transitive' 原因是scala-maven-plugin 插件的配置-make:transitive 有问题,把该行注释掉即可 网上的答案: 删除-make:transitive 或者添加该依赖:最后在服务器提交任务: ./spark-submit --master spark://bigdata00:7077 --executor-memory 512M --total-executor-cores 3 /home/sparkwc.jar hdfs://bigdata00:9000/words hdfs://bigdata00:9000/wordsout2 org.specs2 specs2-junit_${scala.compat.version} 2.4.16 test
