1:spark shell仅在测试和验证我们的程序时使用的较多,在生产环境中,通常会在IDE中编制程序,然后打成jar包,然后提交到集群,最常用的是创建一个Maven项目,利用Maven来管理jar包的依赖。
2:配置Maven的pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

注意:配置好pom.xml以后,点击Enable Auto-Import即可;
3:将src/main/java和src/test/java分别修改成src/main/scala和src/test/scala,与pom.xml中的配置保持一致();
4:新建一个scala class,类型为Object,然后编写spark程序,如下所示:
import org.apache.spark.{SparkConf, SparkContext}
object WordCount {
def main(args: Array[String]): Unit = {
//创建SparkConf()并且设置App的名称
val conf = new SparkConf().setAppName("wordCount");
//创建SparkContext,该对象是提交spark app的入口
val sc = new SparkContext(conf);
//使用sc创建rdd,并且执行相应的transformation和action
sc.textFile(args(0)).flatMap(_.split(" ")).map((_ ,1)).reduceByKey(_ + _,1).sortBy(_._2,false).saveAsTextFile(args(1));
//停止sc,结束该任务
sc.stop();
}
}
5:使用Maven打包:首先修改pom.xml中的mainClass,使其和自己的类路径对应起来:
然后,点击idea右侧的Maven Project选项,点击Lifecycle,选择clean和package,然后点击Run Maven Build:
等待编译完成,选择编译成功的jar包,并将该jar上传到Spark集群中的某个节点上:
记得,启动你的hdfs和Spark集群,然后使用spark-submit命令提交Spark应用(注意参数的顺序):
可以看下简单的几行代码,但是打成的包就将近百兆,都是封装好的啊,感觉牛人太多了。
然后开始进行Spark Submit提交操作,命令如下所示:
[root@master spark-1.6.1-bin-hadoop2.6]# bin/spark-submit \
> --class com.bie.WordCount \
> --master spark://master:7077 \
> --executor-memory 512M \
> --total-executor-cores 2 \
> /home/hadoop/data_hadoop/sparkWordCount-1.0-SNAPSHOT.jar \
> hdfs://master:9000/wordcount.txt \
> hdfs://master:9000/output
或者如下:
bin/spark-submit --class com.bie.WordCount --master spark://master:7077 --executor-memory 512M --total-executor-cores 2 /home/hadoop/data_hadoop/sparkWordCount-1.0-SNAPSHOT.jar hdfs://master:9000/wordcount.txt hdfs://master:9000/outpu
操作如下所示:
可以在图形化页面看到多了一个Application:
然后呢,就出错了,学知识,不出点错,感觉都不正常:

解决思路,百度了一下,也没缕出思路,就只知道是连接超时了,超过了120s,然后呢,我感觉是自己内存设置小了,因为开的虚拟机,主机8G,三台虚拟机,每台分了1G内存,然后设置Spark可以占用800M,跑程序的时候,第一次设置为512M,就连接超时了,第二次设置为了700M,顺利跑完,可以看看跑的过程,还是很有意思的:
