Spark on yarn Intellij ide 安装，编译，打包，集群运行 详解

说明：已经安装好hadoop2.2.0 完全分布，scala，spark已安装好，环境配置完毕；主机为hadoop-master，hadoop-slave

一.intellij 安装（centos6.5系统）

1.需要安装包ideaIc-2017.1.tar.gz（http://pan.baidu.com/s/1nv7Emox）
2.scala jar包 scala-intellij-bin-2017.1.14（http://pan.baidu.com/s/1i4PMZzf）

步骤一。

1.将上述两个安装包放到主节点相关位置（本机放在hadoop-master上，root用户下桌面上）
2.解压 命令如下：
tar zxvf ideaIc-2017.1.tar.gz -C ~/
3.将scala-intellij-bin-2017.1.14 放置在ide-IC-171.3780.95
目录下的 plugins 里面

步骤二。

1.打开intellij
2.新建 Project，如图所示，next

3.project name ，项目名称
project location 为project存放路径
JDK为java（本机之前用centos6.5自带版本1.7，但使用不了，后改为sun公司的1.8）
scala SDK 为2.10.4 （本机安装的版本为2.10.4）

3.
4.在IDEA中开发应用程序时，常常需要通过一定的文件目录组织进行源码编写，例如源文件目录、测试源文件目录，下面演示在Intellij IDEA的src目录下创建main/scala源文件目录。
直接按F4或右键点击工程文件 ，点击OPEN module setting

5.点击Moudules，点击src目录，然后右键创建main/scala文件夹，再点击scala文件夹为sources，如下图所示

6导入Spark 依赖包（本机用spark-assemble-1.0.0-hadoop2.2.0），点击libraries，点击+，点击java，选则spark-assemble-1.0.0-hadoop2.2.0，点击 项目录名称，ok

至此Spark开发环境配置完成

步骤三。本地运行

1.新建 scala object，然后输入代码

2.编译代码，直接Build->build Project
3.然后编程运行参数，Run->Edit Configurations

`/**
* Created by root on 3/28/17.
*/
import org.apache.spark.SparkContext._
import org.apache.spark.{SparkConf, SparkContext}
/**
* Created by root on 3/23/17.
*/
object spp {
def main(args: Array[String]) {
//输入文件既可以是本地linux系统文件，也可以是其它来源文件，例如HDFS
if (args.length == 0) {
System.err.println(“Usage: SparkWordCount ”)
System.exit(1)
}
//以本地线程方式运行，可以指定线程个数，
//如.setMaster(“local[2]”)，两个线程执行
//下面给出的是单线程执行
val conf = new SparkConf().setAppName(“SparkWordCount”).setMaster(“local”)
val sc = new SparkContext(conf)

//wordcount操作，计算文件中包含Spark的行数
val rdd2=sc.textFile(args(0)).flatMap(line => line.split(" ")).map(word => (word,1)).reduceByKey(_+_)
//    val count1=rdd2.countByValue()
//打印结果

// rdd2.saveAsTextFile(path = args(1))
// rdd2.count()
println(rdd2.count())
sc.stop()
}

}

完成后直接Run->Run或Alt+Shift+F10运行程序，执行结果如下图：

OK

打包、集群 yarn 运行

1.看 hdfs 情况
Hadoop fs -ls -R /

2.如上图所示我们已经有了文件1.txt，如果没有，则使用命令将一些好的文件放入hdfs中：hadoop fs -put /usr/local/cluster/hadoop/etc/hadoop/slaves /data/wordcount/
3.修改代码为：
`
package scala
import org.apache.spark.SparkContext._
import org.apache.spark.{SparkConf, SparkContext}
/**
* Created by root on 3/23/17.
*/
object spp {
def main(args: Array[String]) {
//输入文件既可以是本地linux系统文件，也可以是其它来源文件，例如HDFS
if (args.length == 0) {
System.err.println(“Usage: SparkWordCount ”)
System.exit(1)
}
//以本地线程方式运行，可以指定线程个数，
//如.setMaster(“local[2]”)，两个线程执行
//下面给出的是单线程执行
val conf = new SparkConf().setAppName(“SparkWordCount”).setMaster(“spark://10.6.3.200:7077”)
val sc = new SparkContext(conf)

//wordcount操作，计算文件中包含Spark的行数
val rdd2=sc.textFile(args(0)).flatMap(line => line.split(" ")).map(word => (word,1)).reduceByKey(_+_)
//    val count1=rdd2.countByValue()
//打印结果
 rdd2.saveAsTextFile(path = args(1))
//   rdd2.count()
//println(rdd2.count())
sc.stop()

}

}
`
4.点击工程my2，然后按F4打个Project Structure并选择Artifacts，如下图
选择 jar from moulde

5.因为后期提交到集群上运行，因此相关jar包都存在，为减小jar包的体积，将spark-assembly-1.0.0-hadoop2.2.0.jar等jar包删除即可，如下图

6.确定后，再点击Build->Build Artifacts
生成如图所示：

7.运行 yarn-client（cluster会出现内存溢出，未解决）
/root/spark-1.0.0-bin-2.2.0/bin/spark-submit –master yarn-client –class main.scala.spp my2.jar hdfs://hadoop-master:8020/data/wordcount/1.txt hdfs://hadoop-master:8020/data/wordcount/read9

8.看hdfs 是否有read9

看spark ：

集群hdfs：10.6.3.200:50070
spark：10.6.3.200:8088
hadoop：10.6.3.8080
