1：先安装Cygwin
参考http://blog.csdn.net/wind520/article/details/9223003
2：下载
3：解压在C:cygwinhadoop1
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 [INFO ][mgmnt ] Local JMX connector started 13/07/03 15:44:30 INFO namenode.NameNode: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting NameNode STARTUP_MSG: host = lenovo-PC/10.6.3.180 STARTUP_MSG: args = [-format] STARTUP_MSG: version = 1.1.2 STARTUP_MSG: build = https://svn.apache.org/repos/asf/hadoop/common/branches/b ranch-1.1 -r 1440782; compiled by 'hortonfo' on Thu Jan 31 02:03:24 UTC 2013 ************************************************************/ Re-format filesystem in mphadoop-lenovodfs ame ?

第三步，启动Hadoop，执行命令： bin/start-all.sh
需要输入3次密码
lenovo@lenovo-PC /hadoop1 $ bin/start-all.sh starting namenode, logging to /hadoop1/libexec/../logs/hadoop-lenovo-namenode-lenovo-PC.out lenovo@localhost's password: localhost: starting datanode, logging to /hadoop1/libexec/../logs/hadoop-lenovo-datanode-lenovo-PC.out lenovo@localhost's password: localhost: starting secondarynamenode, logging to /hadoop1/libexec/../logs/hadoop-lenovo-secondarynamenode-lenovo-PC.out starting jobtracker, logging to /hadoop1/libexec/../logs/hadoop-lenovo-jobtracker-lenovo-PC.out lenovo@localhost's password: localhost: starting tasktracker, logging to /hadoop1/libexec/../logs/hadoop-lenovo-tasktracker-lenovo-PC.out lenovo@lenovo-PC /hadoop1 $ ps PID PPID PGID WINPID TTY UID STIME COMMAND 59592 1 42744 60224 pty0 1000 15:45:31 /cygdrive/d/java/Tomcat6/jdk/bin/java 58584 58340 58584 58612 pty0 1000 15:43:22 /usr/bin/bash 62296 1 42744 63540 pty0 1000 15:45:48 /cygdrive/d/java/Tomcat6/jdk/bin/java 58844 58584 58844 58936 pty0 1000 15:54:51 /usr/bin/ps 62812 1 62208 63448 ? 1000 15:45:46 /cygdrive/d/java/Tomcat6/jdk/bin/java 58340 1 58340 58340 ? 1000 15:43:22 /usr/bin/mintty lenovo@lenovo-PC /hadoop1 $
hadoop只运行3个JVM进程。
hadoop默认的NameNode 和 JobTracker- NameNode - http://localhost:50070/
- JobTracker - http://localhost:50030/
