hadoop-eclipse-plugin使用

王总兵 — Mon, 23 Apr 2012 06:29:00 GMT

下载hadoop安装包：
http://www.carfab.com/apachesoftware/hadoop/common/hadoop-1.0.2/

但是没有plugin，我到这个地方下载的：
http://ishare.iask.sina.com.cn/f/23642243.html?from=like

copy到你的eclipse_home的plugins下面。

配置map/reduce

你可以看到你的hdfs里面的文件了：

hadoop之mapreduce实例

王总兵 — Thu, 12 Apr 2012 04:50:00 GMT

例子很简单，我没有运行自带的wordcount，而是自己做了一个简单的例子。
实现的功能是从我们的nginx的access log里面计算url访问的次数。
access log文件：

新建maven项目：

Mapper代码如下：

package com.jiexi.examples.hadoop;

import java.io.IOException;

import org.apache.hadoop.io.IntWritable;
import org.apache.hadoop.io.LongWritable;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapred.MapReduceBase;
import org.apache.hadoop.mapred.Mapper;
import org.apache.hadoop.mapred.OutputCollector;
import org.apache.hadoop.mapred.Reporter;

public class AccessLogMapper extends MapReduceBase implements
        Mapper<LongWritable, Text, Text, IntWritable> {
    private final static IntWritable one = new IntWritable(1);
    private Text url = new Text();

    static String POST = "\"POST ";
    static String GET = "\"GET ";
    static String END = " HTTP/1.0";

    public void map(LongWritable key, Text value,
            OutputCollector<Text, IntWritable> output, Reporter reporter)
            throws IOException {
        String line = value.toString();
        String url1 = getUrl(line);

        url.set(url1);
        output.collect(url, one);
    }

    public static void main(String[] args) {
        String a = "10.2.112.34 - - [06/Mar/2012:18:05:41 +0800] \"GET /mine?originUrl= HTTP/1.0\" 302 -";
        String b = "10.2.112.34 - - [06/Mar/2012:15:02:42 +0800] \"POST /user/login?originUrl=http%3A%2F%2Fwww.jiexi.com%2Fhome HTTP/1.0\" 200 25";

//        System.out.println(getUrl(a));
//        System.out.println(getUrl(b));

        String s =" /user/register?originUrl=http%3A%2F%2Fwww.jiexi.com%2Fhome";

        System.out.println(s.substring(0,s.indexOf("?")));
    }

    private static String getUrl(String a) {
        // int len = POST.length();
        int begin = a.indexOf(POST);
        int get = a.indexOf(GET);
        if (get > -1) {
            begin = get;
            // len = GET.length();
        }

        int end = a.indexOf(END);

        String url = a.substring(begin + 1, end);

        if (url.indexOf("?") > 0) {
            return url.substring(0, url.indexOf("?"));
        }

        return url;
    }

}

Reducer代码如下：

package com.jiexi.examples.hadoop;

import java.io.IOException;
import java.util.Iterator;

import org.apache.hadoop.io.IntWritable;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapred.MapReduceBase;
import org.apache.hadoop.mapred.OutputCollector;
import org.apache.hadoop.mapred.Reducer;
import org.apache.hadoop.mapred.Reporter;

public class AccessLogReducer extends MapReduceBase implements
        Reducer {

    public void reduce(Text key, Iterator values,
            OutputCollector output, Reporter reporter)
            throws IOException {
        int sum = 0;
        while (values.hasNext()) {
            sum += values.next().get();
        }
        output.collect(key, new IntWritable(sum));
    }

}

job调用

package com.jiexi.examples.hadoop;

import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IntWritable;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapred.FileInputFormat;
import org.apache.hadoop.mapred.FileOutputFormat;
import org.apache.hadoop.mapred.JobClient;
import org.apache.hadoop.mapred.JobConf;
import org.apache.hadoop.mapred.TextInputFormat;
import org.apache.hadoop.mapred.TextOutputFormat;

public class AccessLogPerDayJob {
    public static void main(String[] args) throws Throwable {
        JobConf jobConf = new JobConf(AccessLogPerDayJob.class);
        jobConf.setJobName("access_log");

        jobConf.setOutputKeyClass(Text.class);
        jobConf.setOutputValueClass(IntWritable.class);

        jobConf.setMapperClass(AccessLogMapper.class);
        jobConf.setCombinerClass(AccessLogReducer.class);
        jobConf.setReducerClass(AccessLogReducer.class);

        jobConf.setInputFormat(TextInputFormat.class);
        jobConf.setOutputFormat(TextOutputFormat.class);

        FileInputFormat.addInputPath(jobConf, new Path(args[0]));
        FileOutputFormat.setOutputPath(jobConf, new Path(args[1]));

        JobClient.runJob(jobConf);
    }
}

===============================================
mvn clean package
丢到namenode的/opt/hadoop 下面

运行：
./bin/hadoop dfs -mkdir access_log_in
./bin/hadoop dfs -ls

#拷贝本地日志文件到hdfs中
./bin/hadoop dfs -put /opt/access_log/* access_log_in

#运行，把access_log.jar拷贝到/opt/hadoop下面

hadoop安装小记

王总兵 — Wed, 11 Apr 2012 11:14:00 GMT

#准备工作
准备3台机器，建立相同的用户名和密码，如：root/jiexi_test
分别如下：
10.2.112.31 #namenode
10.2.112.30 #datanode
10.2.112.34 #datanode

重点：
1、使用ssh-keygen生成id_rsa.pub文件，使3台机器可以相互ssh而不需要输入密码。
2、关闭掉防火墙。

参照文章：
http://qinlong.blog.51cto.com/1130504/323086 设置ssh-keygen

spring-data-jpa使用的一个小问题

王总兵 — Fri, 23 Mar 2012 04:42:00 GMT

在使用spring-data-jpa的时候，我习惯性的没使用@Service，而是在xml文件里面定义了service bean。
而这时，在service类里面@Autowired的XXXXXXRepository提示空指针异常。
这个问题在我的testcase里面是不存在，也就是说，使用AbstractTransactionalJUnit4SpringContextTests进行加载xml文件的方式，所有的bean都可以准确的注入。
后来我换了@Service方式，加入就可以了。
怀疑是spring的data-jpa定义的XXXXXXRepository在web模式下面加载到application context里面出了问题。
也有可能是因为我的xxxxx-servlet.xml文件里面哪里定义不对导致的。

json和javascript的关系

王总兵 — Tue, 20 Mar 2012 13:19:00 GMT

参考json网站： http://www.json.org/json-zh.html

JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式。易于人阅读和编写。同时也易于机器解析和生成。它基于JavaScript Programming Language,Standard ECMA-262 3rd Edition - December 1999的一个子集。 JSON采用完全独立于语言的文本格式，但是也使用了类似于C语言家族的习惯（包括C, C++, C#, Java, JavaScript, Perl, Python等）。这些特性使JSON成为理想的数据交换语言。

maven+jetty开发实例

王总兵 — Thu, 08 Jul 2010 12:27:00 GMT

  最近准备离职了，等着到20号离开。所以在公司里面没有什么事情，自己研究了一下maven。以前对他的认识主要是依赖管理，而这几天的学习，对他的plugin机制影响特别深刻。特别的是jetty插件的使用，十分方便。

  首先需要下载eclipse，推荐最新的Helios版本，安装m2eclipse插件，更新地址为：http://m2eclipse.sonatype.org/sites/m2e/0.10.2.20100623-1649/。新建一个maven项目，并且使用下面的pom文件。具体代码如下：

  在eclipse中选择菜单run-》external tools进入，配置2个命令：jetty_run和jetty_stop。其中run命令location为$MAVEN_HOME/bin/mvn.bat，working directory选择当前项目即可，参数输入：-Dslf4j=false -Dlog4j.configuration=file:./target/classes/log4j.properties jetty:run。
  stop命令和run命令前面2项相同，参数输入：jetty:stop。

  配置完上面的东西，你马上可以开始一个maven+jetty项目，运行run即可访问http://localhost:8080访问web页面，运行stop关闭服务器。
