首先我们需要根据日志信息抽取出浏览器信息,针对不同的浏览器进行统计操作。虽然可以自己实现这个功能,但是懒得再造轮子了,所以我在GitHub找到了一个小工具可以完成这个功能,GitHub地址如下:
https://github.com/LeeKemp/UserAgentParser
通过git clone或者浏览器下载到本地后,使用命令行进入到其主目录下,然后通过maven命令对其进行打包并安装到本地仓库里:
$ mvn clean package -DskipTest
$ mvn clean install -DskipTest
安装完成后,在工程中添加依赖以及插件:
cloudera
https://repository.cloudera.com/artifactory/cloudera-repos/
true
false
UTF-8
2.6.0-cdh6.7.0
org.apache.hadoop
hadoop-client
${hadoop.version}
provided
com.kumkee
UserAgentParser
0.0.1
junit
junit
4.10
test
maven-assembly-plugin
jar-with-dependencies
然后我们编写一个测试用例来测试一下这个解析类,因为之前并没有使用过这个工具,所以对于一个未使用过的工具,要养成在工程中使用之前对其进行测试的好习惯:
package org.zero01.project;
import com.kumkee.userAgent.UserAgent;
import com.kumkee.userAgent.UserAgentParser;
/**
* @program: hadoop-train
* @description: UserAgent解析测试类
* @author: 01
* @create: 2018-04-01 22:43
**/
public class UserAgentTest {
public static void main(String[] args) {
String source = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36";
UserAgentParser userAgentParser = new UserAgentParser();
UserAgent agent = userAgentParser.parse(source);
String browser = agent.getBrowser();
String engine = agent.getEngine();
String engineVersion = agent.getEngineVersion();
String os = agent.getOs();
String platform = agent.getPlatform();
boolean isMobile = agent.isMobile();
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("是否是移动设备:" + isMobile);
}
}
控制台输出结果如下:
浏览器:Chrome
引擎:Webkit
引擎版本:537.36
操作系统:Windows 7
平台:Windows
是否是移动设备:false
从打印结果可以看到,UserAgent的相关信息都正常获取到了,我们就可以在工程中进行使用这个工具了。
创建一个类,编写代码如下:
package org.zero01.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.fs.Path;
import org.apache.hadoop.io.LongWritable;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapreduce.Job;
import org.apache.hadoop.mapreduce.Mapper;
import org.apache.hadoop.mapreduce.Reducer;
import org.apache.hadoop.mapreduce.lib.input.FileInputFormat;
import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

System.out.println("output file exists, but is has deleted");
}

}
在工程目录下打开控制台,输入如下命令进行打包:
mvn assembly:assembly
打包成功:
将这个jar包上传到服务器上:
[root@localhost ~]# rz # 使用的是Xshell工具,所以直接使用rz命令即可上传文件
[root@localhost ~]# ls |grep hadoop-train-1.0-jar-with-dependencies.jar # 查看是否上传成功
hadoop-train-1.0-jar-with-dependencies.jar
[root@localhost ~]#
把事先准备好的日志文件上传到HDFS文件系统中:
[root@localhost ~]# hdfs dfs -put ./10000_access.log /
[root@localhost ~]# hdfs dfs -ls /10000_access.log
-rw-r--r-- 1 root supergroup 2769741 2018-04-02 22:33 /10000_access.log
[root@localhost ~]#
执行如下命令
[root@localhost ~]# hadoop jar ./hadoop-train-1.0-jar-with-dependencies.jar org.zero01.hadoop.project.LogApp /10000_access.log /browserout
执行成功:
查看处理结果:
[root@localhost ~]# hdfs dfs -ls /browserout
