基于IDEA环境下的Spark2.X程序开发

我们选择在线安装

这个是windows下的scala,直接双击安装就可以了

安装好之后可以验证一下

这个是我本地的jdk1.8安装包，直接双击安装

安装完成后可以验证一下

https://archive.apache.org/dist/maven/maven-3/3.3.9/binaries/

解压

我的本地是win10系统

配置好环境变量我们可以验证一下

修改这个文件

这个是默认的

改成这样子

把本地的maven配置进来

接下来就是等待自动把相应的架包下载下来

把scala添加进来了

接下来我们创建目录

在scala目录下建包

在这个包里面创建一个scala的类

输入以下代码

配置maven的 pom.xml文件

在Test.scala里加上这段内容

我们编写一个简单的代码

package com.spark.test

import org.apache.spark.sql.SparkSession

object Test {

  def main(args: Array[String]): Unit = {
   val spark= SparkSession
       .builder
         .appName("HdfsTest")
           .getOrCreate()
     val filePart = "E://Mycode/datas/stu.txt"
     val rdd= spark.sparkContext.textFile(filePart)

     val lines= rdd.flatMap(x => x.split(" ")).collect().toList
     println(lines)
  }
}

运行一下

结果报错了

这是因为我本地没有配置好hadoop,现在我们配一个

这个是我本地的hadoop/bin

下面把本地win10的环境变量配置一下

再重启一下idea,再运行一下程序

报了另外一个错误，但是可以确定的是前面的错误我们解决了

这里的错误是说要指明你的程序运行在什么地方

在程序里加上这一句，指明我们现在在本地运行

我们再运行一次，可以看到没问题了

我们继续修改程序，加上这一句

再次运行看看结果

把相同的单词进行累加

我们看看运行结果

刚刚我们使用的是rdd的方式，接下来我们使用dataSet的方式

dataSet可以近似的理解为数据库的一张张表

我们运行的结果

用空格切分单词

运行结果

分组统计

运行结果

把最后的代码放上来

package com.spark.test

import org.apache.spark.sql.SparkSession
import org.apache.spark.{SparkConf, SparkContext}
object Test {

  def main(args: Array[String]): Unit = {
   val spark= SparkSession
       .builder
         .master("local")
         .appName("HdfsTest")
           .getOrCreate()
     val filePart = "E://Mycode/datas/stu.txt"
//     val rdd= spark.sparkContext.textFile(filePart)
//     val lines= rdd.flatMap(x => x.split(" ")).map(x=>(x,1)).reduceByKey((a,b)=>(a+b)).collect().toList
    //     println(lines)
    import spark.implicits._
    val dataSet= spark.read.textFile(filePart)
      .flatMap(x => x.split(" "))
      .map(x=>(x,1)).groupBy("_1").count()
      .show()
    
  }
}

现在我们把程序打包

我们把代码稍微改一下

package com.spark.test

import org.apache.spark.sql.SparkSession
import org.apache.spark.{SparkConf, SparkContext}
object Test {

  def main(args: Array[String]): Unit = {
   val spark= SparkSession
       .builder
         .master("local")
         .appName("HdfsTest")
           .getOrCreate()

    val filePart = args(0)
    //  val filePart = "E://Mycode/datas/stu.txt"
//     val rdd= spark.sparkContext.textFile(filePart)
//     val lines= rdd.flatMap(x => x.split(" ")).map(x=>(x,1)).reduceByKey((a,b)=>(a+b)).collect().toList
    //     println(lines)
    import spark.implicits._
    val dataSet= spark.read.textFile(filePart)
      .flatMap(x => x.split(" "))
      .map(x=>(x,1)).groupBy("_1").count()
      .show()

  }
}

把这些都剔除掉

剩下这两个

打包完成了

把这个包上传到我们的集群上

这个是我们的数据文件

我们把数据文件上传的hdfs上面去，先启动hdfs

同时记得把zookeeper也启动了，不然会出问题的

现在hdfs上创建一个目录

把本地的文件上传

我们在集群上跑一下

bin/spark-submit --master local[2] /opt/jars/sparkStu.jar hdfs://bigdata-pro01.kfk.com:9000/user/datas/stu.txt

可以看到跑下来的结果
