流程示意图:
需求:
日志片段如下:

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:
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:
-
<repositories>
-

-

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.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;
-

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
-
Found 2 items
