a. 简单统计网站的访问日志中每个浏览器的访问次数
a. 请参考文章:大数据日志分析系统背景及架构
a. 可以用来解析http user-agent信息的小工具(别人写好的小项目)
a. 信息样式
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.81 Safari/537.36
b. 查看user-agent(进入网站按F12进入检查界面,刷新一下)
a. 下载地址(可以用git或者直接下载压缩包然后解压):
https://github.com/LeeKemp/UserAgentParser
a. 用Maven打包小工具成jar包(进入主目录,如:E:\workspace\UserAgentParser-master)
mvn clean package -DskipTest
b. 安装jar包到本地Maven仓库
mvn clean install -DskipTest
a. 可参考此文章的0x01 新建maven工程
:
Java API实现HDFS的相关操作
a. 引入依赖(如果没有在安装此jar到本地仓库是无法引入的)
<dependency>
<groupId>com.kumkeegroupId>
<artifactId>UserAgentParserartifactId>
<version>0.0.1version>
dependency>
b. 完整的依赖

a. 在java的测试目录创建一个测试包(com.shaonaiyi.hadoop.project
):
b. 新建UserAgentTest测试类:
package com.shaonaiyi.hadoop.project;
import com.kumkee.userAgent.UserAgent;
import com.kumkee.userAgent.UserAgentParser;
/**
* @Auther: 邵奈一
* @Date: 2019/03/27 下午 2:45
* @Description: UserAgent解析测试类
*/
public class UserAgentTest {
public static void main(String[] args) {
String agentSource = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.81 Safari/537.36";
UserAgentParser userAgentParser = new UserAgentParser();
UserAgent agent = userAgentParser.parse(agentSource);
String browser = agent.getBrowser();
String engine = agent.getEngine();
String engineVersion = agent.getEngineVersion();
String os = agent.getOs();
String platform = agent.getPlatform();
boolean isMobile = agent.isMobile();
String version = agent.getVersion();
System.out.println("浏览器:" + browser);
System.out.println("引擎:" + engine);
System.out.println("引擎版本:" + engineVersion);
System.out.println("操作系统:" + os);
System.out.println("平台:" + platform);
System.out.println("是否为移动设备:" + isMobile);
System.out.println("版本号:" + version);
}
}
a. 新建包
b. 新建ParseUserAgentApp类:
package com.shaonaiyi.hadoop.project;
import com.kumkee.userAgent.UserAgent;
import com.kumkee.userAgent.UserAgentParser;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.FileSystem;

import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
/**

}
Job job = Job.getInstance(configuration, "ParseUserAgentApp");
job.setJarByClass(ParseUserAgentApp.class);
job.setMapperClass(MyMapper.class);

job.setMapOutputValueClass(LongWritable.class);
job.setReducerClass(MyReducer.class);
job.setOutputKeyClass(Text.class);
job.setOutputValueClass(LongWritable.class);
FileInputFormat.setInputPaths(job, new Path(args[0]));
FileOutputFormat.setOutputPath(job, new Path(args[1]));
System.exit(job.waitForCompletion(true) ? 0 : 1);
}
}
ps:代码其实是此教程:MapReduce入门例子之单词计数 改写来的,请查看学习!
c. 打包(怎么打包都可以,此处教一种新的打包方式)
mvn assembly:assembly
a. 打包好项目后,可以在target目录看到有两个包:
hadoop-learning-1.0.jar
:没有引入外部依赖的jar包(在本地windows可以用而已)
hadoop-learning-1.0-jar-with-dependencies.jar
:引入了外部依赖的jar包(含小工具jar包)
说明:因为我们的服务器没有我们刚开始时打包的UserAgentParser-0.0.1.jar
包,我们只是在我们windows系统本地打了jar包,并安装到了我们windows系统的Maven仓库,实际上我们的服务器上没有的,所以要将hadoop-learning-1.0-jar-with-dependencies.jar
此包拷贝到服务器使用,不然的话也要在服务器的Maven仓库安装好UserAgentParser-0.0.1.jar
才行。
b. 上传项目到服务器
[hadoop-sny@master mr]$ pwd
/home/hadoop-sny/mr
[hadoop-sny@master mr]$ ll

b. 上传日志到HDFS根目录
hadoop fs -put access.log /files
a. 请确保HDFS与YARN已启动,并确保HDFS根目录有access.log
文件
b. 进入jar包所在目录(此处为:/home/hadoop-sny/mr
)
cd /home/hadoop-sny/mr
c. 执行:
hadoop jar ./hadoop-learning-1.0-jar-with-dependencies.jar com.shaonaiyi.hadoop.project.ParseUserAgentApp /files/access.log /projectout
d. 查看统计结果
hadoop fs -cat /projectout/*
结果显示:
[hadoop-sny@master mr]$ hadoop fs -cat /projectout/*
