[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>0.96.2-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)) { 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 { 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()); // // 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
报错：

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。
