准备:
确保hadoop2.2.0集群正常运行
1.eclipse中建立mven工程,并编辑pom文件如下
 <dependencies>
        <dependency>
            <groupId>org.apache.hbase</groupId>
            <artifactId>hbase-client</artifactId>
            <version>0.96.2-hadoop2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-hdfs</artifactId>
            <version>2.2.0</version>
        </dependency>
        <dependency>
            <groupId>jdk.tools</groupId>
            <artifactId>jdk.tools</artifactId>
            <version>1.7</version>
            <scope>system</scope>
            <systemPath>${JAVA_HOME}/lib/tools.jar</systemPath>
        </dependency>
    </dependencies>

2.在src/main/resources根目录下拷入log4j.properties,通过log4j查看详细日志

log4j.rootLogger=debug, stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p - %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=firestorm.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
log4j.logger.com.codefutures=DEBUG

3.拷入一个可执行的hadoop程序,我用的是一个HdfsDAO,可以先保证HDFS操作能执行

package com.bigdata.hdfs;

import java.io.IOException;
import java.net.URI;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.FSDataInputStream;
import org.apache.hadoop.fs.FSDataOutputStream;
import org.apache.hadoop.fs.FileStatus;
import org.apache.hadoop.fs.FileSystem;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IOUtils;
import org.apache.hadoop.mapred.JobConf;

public class HdfsDAO {
    private static final String HDFS = "hdfs://192.168.11.37:9000/";
    
    
    public HdfsDAO(Configuration conf) {
        this(HDFS, conf);
    }
    
    public HdfsDAO(String hdfs, Configuration conf) {
        this.hdfsPath = hdfs;
        this.conf = conf;
    }
    private String hdfsPath;
    private Configuration conf;
    public static void main(String[] args) throws IOException {
        JobConf conf = config();
        HdfsDAO hdfs = new HdfsDAO(conf);
//        hdfs.copyFile("datafile/item.csv", "/tmp/new");
//        hdfs.ls("/tmp/new");
        hdfs.ls("/");
    }        
    
    public static JobConf config(){
        JobConf conf = new JobConf(HdfsDAO.class);
        conf.setJobName("HdfsDAO");
        conf.addResource("classpath:/hadoop/core-site.xml");
        conf.addResource("classpath:/hadoop/hdfs-site.xml");
        conf.addResource("classpath:/hadoop/mapred-site.xml");
        return conf;
    }
    
    public void mkdirs(String folder) throws IOException {
        Path path = new Path(folder);
        FileSystem fs = FileSystem.get(URI.create(hdfsPath), conf);
        if (!fs.exists(path)) {

            System.out.println("Create: " + folder);
        }
        fs.close();
    }
    public void rmr(String folder) throws IOException {
        Path path = new Path(folder);
        FileSystem fs = FileSystem.get(URI.create(hdfsPath), conf);
        fs.deleteOnExit(path);
        System.out.println("Delete: " + folder);
        fs.close();
    }
    public void ls(String folder) throws IOException {
        Path path = new Path(folder);
        FileSystem fs = FileSystem.get(URI.create(hdfsPath), conf);
        FileStatus[] list = fs.listStatus(path);
        System.out.println("ls: " + folder);
        System.out.println("==========================================================");
        for (FileStatus f : list) {
            System.out.printf("name: %s, folder: %s, size: %d\n", f.getPath(), f.isDir(), f.getLen());
        }
        System.out.println("==========================================================");
        fs.close();
    }
    public void createFile(String file, String content) throws IOException {
        FileSystem fs = FileSystem.get(URI.create(hdfsPath), conf);
        byte[] buff = content.getBytes();
        FSDataOutputStream os = null;
        try {
            os = fs.create(new Path(file));
            os.write(buff, 0, buff.length);
            System.out.println("Create: " + file);
        } finally {
            if (os != null)
                os.close();
        }
        fs.close();
    }
    public void copyFile(String local, String remote) throws IOException {
        FileSystem fs = FileSystem.get(URI.create(hdfsPath), conf);
        fs.copyFromLocalFile(new Path(local), new Path(remote));
        System.out.println("copy from: " + local + " to " + remote);
        fs.close();
    }
    public void download(String remote, String local) throws IOException {
        Path path = new Path(remote);
        FileSystem fs = FileSystem.get(URI.create(hdfsPath), conf);
        fs.copyToLocalFile(path, new Path(local));
        System.out.println("download: from" + remote + " to " + local);
        fs.close();
    }
    
    public void cat(String remoteFile) throws IOException {
        Path path = new Path(remoteFile);
        FileSystem fs = FileSystem.get(URI.create(hdfsPath), conf);
        FSDataInputStream fsdis = null;
        System.out.println("cat: " + remoteFile);
        try {  
            fsdis =fs.open(path);
            IOUtils.copyBytes(fsdis, System.out, 4096, false);  
          } finally {  
            IOUtils.closeStream(fsdis);
            fs.close();
          }
    }
    public void location() throws IOException {
        // String folder = hdfsPath + "create/";
        // String file = "t2.txt";
        // FileSystem fs = FileSystem.get(URI.create(hdfsPath), new
        // Configuration());
        // FileStatus f = fs.getFileStatus(new Path(folder + file));
        // BlockLocation[] list = fs.getFileBlockLocations(f, 0, f.getLen());
        //

        // }
        // }

    }

}

4.运行HdfsDAO

解决:
首先,在win7中设置环境变量HADOOP_HOME,指向win7中的hadoop2.2.0根目录。
然后,到 https://github.com/srccodes/hadoop-common-2.2.0-bin 去下载hadoop2.2.0的bin,里面有winutils.exe
将其拷贝到 $HADOOP_HOME/bin 下。
5.重新启动,顺利执行

总结:
1.将hadoop-2.2.0.tar.gz解压一份放到win7的程序目录下,注意hadoop版本一定要和集群的版本一致,然后拷贝集群中的以下几个配置文件覆盖到win7本地的对应目录:
core-site.xml
hdfs-site.xml
mapred-site.xml
yarn-site.xml
 
2.在eclipse中新建java工程后,最好直接引入所有hadoop2.2.0相关的jar包,包括以下几个目录下的jar包:
share\hadoop\common
share\hadoop\hdfs
share\hadoop\mapreduce
share\hadoop\yarn
 
注:如果使用hadoop的eclipse插件,就无需该步骤,但2.2.0的插件需自行编译,编译过程参见我的另一篇博客:
 
3.需要在win7中设置环境变量%HADOOP_HOME%,并把%HADOOP_HOME%\bin加入PATH环境变量中
 
4.需要下载https://github.com/srccodes/hadoop-common-2.2.0-bin,解压后把下载的bin目录覆盖%HADOOP_HOME%\bin
 
5.注意参考hadoop集群的配置,Eclipse中的程序配置“hadoop地址:端口”的代码需和hadoop集群的配置一致
<property>
    <name>fs.default.name</name>
    <value>hdfs://singlehadoop:8020</value>
</property>
 
6.在hadoop集群的hdfs-site.xml中加入如下属性,关闭权限校验。
<property>     
    <name>dfs.permissions</name>    
    <value>false</value>
</property>
 
7.hbase文件设置

<property>
<name>hbase.zookeeper.quorum</name>
<value>compute1</value>
</property>

一定要配置 quorum 的值为 hostname,  节点个数必须为子节点而且要为奇数个。

在Windows 的 C:\Windows\System32\drivers\etc  目录下修改hosts映射文件,与集群服务器的映射文件保持一致。

192.168.14.20 CS020
