       通过上文 Window7 开发 Spark 应用 ,展示了如何开发一个Spark应用,但文中使用的测试数据都是自己手动录入的。

所以本文讲解一下如何搭建一个开发闭环,本里使用了Nginx日志采集分析为例,分析页面访问最多的10个,404页面的10。

如果把这些开发成果最终展示到一个web网页中,在这篇文章中就不描述了,本博其他文章给出的示例已经足够你把Spark的应用能力暴露到Web中。

应用开发

1. 本地新建一个Spark项目,POM.xml 内容如下:

4.0.0com.phpdragon
    spark-example
    1.0-SNAPSHOTUTF-82.4.52.12org.apache.spark
            spark-core_${spark.scala.version}

2. 编写Nginx日志分析代码:

准备工作

1.请查看文章, Centos7 搭建 Flume 采集 Nginx 日志 。

2.执行测试脚本,增加访问日志:

本地调试

1.增加红色部分代码,设置为本地模式 。

2.右键执行main方法:
