[开发]Win7环境下Eclipse连接Hadoop2.2.0
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.-hadoop2</version>
</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-hdfs</artifactId>
<version>2.2.</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=
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;

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)) {
fs.mkdirs(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 {

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, , 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, , 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());
//
// System.out.println("File Location: " + folder + file);
// for (BlockLocation bl : list) {
// String[] hosts = bl.getHosts();
// for (String host : hosts) {
// System.out.println("host:" + host);
// }
// }
// fs.close();
} }
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。
