hadoop-1.1.2 在Windows环境下的部署

1：先安装Cygwin

参考http://blog.csdn.net/wind520/article/details/9223003

2：下载

3：解压在C:\cygwin\hadoop1

4：配置

hadoop1/conf下需要配置的文件：

1).hadoop-env.sh

2).core-site.xml

3).hdfs-site.xml

4).mapred-site.xml

如何修改请参考 http://blog.csdn.net/wind520/article/details/9225429

5：启动Hadoop

第一步，在hadoop1目录下创建目录logs，用于保存日志
第二步，Format a new distributed-filesystem: 格式化namenode，创建HDFS
执行命令： bin/hadoop namenode -format

开始没有格式化，导致打不开

• NameNode - http://localhost:50070/

  lenovo@lenovo-PC ~
  $ cd ..
   
  lenovo@lenovo-PC /home
  $ cd hadoop1
  -bash: cd: hadoop1: No such file or directory
   
  lenovo@lenovo-PC /home
  $ cd ../hadoop1
   
  lenovo@lenovo-PC /hadoop1
  $ bin/hadoop namenode -format

  第三步，启动Hadoop，执行命令： bin/start-all.sh

  需要输入3次密码

  $ bin/start-all.sh

  hadoop只运行3个JVM进程。

  hadoop默认的NameNode 和 JobTracker

  • NameNode - http://localhost:50070/
  • JobTracker - http://localhost:50030/
