eclipse开发spark程序配置在集群上运行

这篇bolg讲一下，IDE开发的spark程序如何提交到集群上运行。
首先保证你的集群是运行成功的，集群搭建可以参考http://kevin12.iteye.com/blog/2273556

开发集群测试的spark wordcount程序；
1.hdfs数据准备.
先将README.md文件上传到hdfs上的/library/wordcount/input2目录
root@master1:/usr/local/hadoop/hadoop-2.6.0/sbin# hdfs dfs -mkdir /library/wordcount/input2
root@master1:/usr/local/hadoop/hadoop-2.6.0/sbin# hdfs dfs -put /usr/local/tools/README.md /library/wordcount/input2
查看一下确保文件已经上传到hdfs上。


程序代码：

package com.imf.spark

import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
/**
 * 用户scala开发集群测试的spark wordcount程序
 */
object WordCount_Cluster {
   def main(args: Array[String]): Unit = {
     /**
      * 1.创建Spark的配置对象SparkConf，设置Spark程序的运行时的配置信息，
      * 例如：通过setMaster来设置程序要链接的Spark集群的Master的URL,如果设置为local,
      * 则代表Spark程序在本地运行，特别适合于机器配置条件非常差的情况。
      */
     //创建SparkConf对象
     val conf = new SparkConf()
     //设置应用程序名称，在程序运行的监控界面可以看到名称
     conf.setAppName("My First Spark App!")
     /**
      * 2.创建SparkContext对象
      * SparkContext是spark程序所有功能的唯一入口，无论是采用Scala,java,python,R等都必须有一个SprakContext
      * SparkContext核心作用：初始化spark应用程序运行所需要的核心组件，包括DAGScheduler,TaskScheduler,SchedulerBackend
      * 同时还会负责Spark程序往Master注册程序等；
      * SparkContext是整个应用程序中最为至关重要的一个对象；
      */
     //通过创建SparkContext对象，通过传入SparkConf实例定制Spark运行的具体参数和配置信息
     val sc = new SparkContext(conf)

     /**
      * 3.根据具体数据的来源（HDFS,HBase,Local,FS,DB,S3等）通过SparkContext来创建RDD；
      * RDD的创建基本有三种方式：根据外部的数据来源（例如HDFS）、根据Scala集合、由其他的RDD操作；
      * 数据会被RDD划分成为一系列的Partitions,分配到每个Partition的数据属于一个Task的处理范畴；
      */
     //读取hdfs文件内容并切分成Pratitions
     //val lines = sc.textFile("hdfs://master1:9000/library/wordcount/input2")
     val lines = sc.textFile("/library/wordcount/input2")//这里不设置并行度是spark有自己的算法，暂时不去考虑

     /**
      * 4.对初始的RDD进行Transformation级别的处理，例如map,filter等高阶函数的变成，来进行具体的数据计算
      * 4.1.将每一行的字符串拆分成单个单词
      */
     //对每一行的字符串进行拆分并把所有行的拆分结果通过flat合并成一个大的集合
      val words = lines.flatMap { line => line.split(" ") }
     /**
      * 4.2.在单词拆分的基础上对每个单词实例计数为1，也就是word => (word,1)
      */
     val pairs = words.map{word =>(word,1)}

     /**
      * 4.3.在每个单词实例计数为1基础上统计每个单词在文件中出现的总次数
      */
     //对相同的key进行value的累积（包括Local和Reducer级别同时Reduce）
     val wordCounts = pairs.reduceByKey(_+_)
     //打印输出
     wordCounts.collect.foreach(pair => println(pair._1+":"+pair._2))
     sc.stop()
   }
}

2.打包程序
将程序打包成jar文件，并将jar文件复制到虚拟机的master1上的/usr/local/sparkApps目录下。



3.提交应用程序到集群中。
可以参考官方文档http://spark.apache.org/docs/latest/submitting-applications.html
第一次用的是下面的命令，结果运行不了，提示信息和命令如下：原因没有提交到集群中。

root@master1:/usr/local/spark/spark-1.6.0-bin-hadoop2.6/bin# ./spark-submit \
> --class com.imf.spark.WordCount_Cluster \
> --master master spark://master1:7077 \
> /usr/local/sparkApps/WordCount.jar
Error: Master must start with yarn, spark, mesos, or local
Run with --help for usage help or --verbose for debug output

第二次修改命令如下，运行正常：

./spark-submit \
--class com.imf.spark.WordCount_Cluster \
--master yarn \
/usr/local/sparkApps/WordCount.jar

运行结果如下：

root@master1:/usr/local/spark/spark-1.6.0-bin-hadoop2.6/bin# ./spark-submit \
> --class com.imf.spark.WordCount_Cluster \
> --master yarn \
> /usr/local/sparkApps/WordCount.jar

运行结果和本地的一样。

4.通过写一个wordcount.sh，实现自动化。
创建一个wordcount.sh文件，内容如下，保存并退出。然后chmod +x wordcount.sh给shell文件执行权限。运行下面的命令，执行即可，执行结果和上面的一样。

root@master1:/usr/local/sparkApps# ./wordcount.sh

6.通过浏览器查看程序运行结果：
