hgs19921112發表於2018-10-08
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
啟動spark shell
./spark-shell  --master spark://bigdata00:7077 --executor-memory 512M 
用spark shell 完成一個wordcount
scala> sc.textFile("hdfs://bigdata00:9000/words").flatMap(_.split(" ")).map((_,1)).reduceByKey(_+_).collect
結果:
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))
//主類
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
  }
}

最後在build assembly:assembly的時候出現以下問題
      scalac error: bad option: '-make:transitive'
      原因是scala-maven-plugin 外掛的配置 <arg>-make:transitive</arg> 有問題,把該行註釋掉即可
      
      網上的答案:
      刪除<arg>-make:transitive</arg> 
      或者新增該依賴:
<dependency>
<groupId>org.specs2</groupId>
<artifactId>specs2-junit_${scala.compat.version}</artifactId>
<version>2.4.16</version>
<scope>test</scope>
</dependency>
最後在伺服器提交任務:
./spark-submit --master spark://bigdata00:7077  --executor-memory 512M --total-executor-cores 3  /home/sparkwc.jar   hdfs://bigdata00:9000/words  hdfs://bigdata00:9000/wordsout2
