对于maven创建spark项目的pom.xml配置文件（图文详解）

　不多说，直接上干货！

 

http://mvnrepository.com/

 

 

 

 

 

 

　　这里，怎么创建，见

Spark编程环境搭建（基于Intellij IDEA的Ultimate版本）（包含Java和Scala版的WordCount）（博主强烈推荐)

 

 

 

　　这里， 我重点说下spark项目，因为，对于hadoop这样的，我已经写了大量博客了。

 　　比如，我目前用得较多的spark-mllib。

　　这里spark-mllib_2.10 就是你的scala版本是2.10.X系列。比如我一般是使用scala-2.10.4。

　　这里spark-mllib_2.11 就是你的scala版本是2.11.X系列。

 

 

 

 

　　同时，大家要养成规范，http://mvnrepository.com里是示例如下

复制代码
<!-- https://mvnrepository.com/artifact/org.apache.spark/spark-mllib_2.10 -->
<dependency>
    <groupId>org.apache.spark</groupId>
    <artifactId>spark-mllib_2.10</artifactId>
    <version>2.2.0</version>
    <scope>provided</scope>
</dependency>
复制代码

 

 

　　

 　　但是呢，我不建议这样。反而是把版本抽取出来，

 

 

 

 　　以下是我的maven构建出来的spark项目的pom.xml，大家可以作为参考下。当然这不是最规范的。
