Win7+Cygwin+Hadoop1.0.3安装

捣鼓了两三天，参考了好多资料，终于在win7/Cygwin/Hadoop1.0.3下跑通了自带例子。
注意事项如下：

一 安装Cygwin，注意要选中Net分类下的Openssh

二 在Cygwin下安装SSH，步骤如下：

$ ssh-host-config

*** Query: Overwrite existing /etc/ssh_config file? (yes/no) yes
*** Info: Creating default /etc/ssh_config file
*** Query: Overwrite existing /etc/sshd_config file? (yes/no) yes
*** Info: Creating default /etc/sshd_config file
*** Info: Privilege separation is set to yes by default since OpenSSH 3.3.
*** Info: However, this requires a non-privileged account called 'sshd'.
*** Info: For more info on privilege separation read /usr/share/doc/openssh/README.privsep.
*** Query: Should privilege separation be used? (yes/no) no
*** Info: Updating /etc/sshd_config file

*** Query: Do you want to install sshd as a service?
*** Query: (Say "no" if it is already installed as a service) (yes/no) yes
*** Query: Enter the value of CYGWIN for the daemon: []
*** Info: On Windows Server 2003, Windows Vista, and above, the
*** Info: SYSTEM account cannot setuid to other users -- a capability
*** Info: sshd requires.  You need to have or to create a privileged
*** Info: account.  This script will help you do so.

*** Info: You appear to be running Windows XP 64bit, Windows 2003 Server,
*** Info: or later.  On these systems, it's not possible to use the LocalSystem
*** Info: account for services that can change the user id without an
*** Info: explicit password (such as passwordless logins [e.g. public key
*** Info: authentication] via sshd).

*** Info: If you want to enable that functionality, it's required to create
*** Info: a new account with special privileges (unless a similar account
*** Info: already exists). This account is then used to run these special
*** Info: servers.

*** Info: Note that creating a new user requires that the current account
*** Info: have Administrator privileges itself.

*** Info: No privileged account could be found.

*** Info: This script plans to use 'cyg_server'.
*** Info: 'cyg_server' will only be used by registered services.
*** Query: Do you want to use a different name? (yes/no) yes
*** Query: Enter the new user name: hadoop
*** Query: Reenter: hadoop

*** Query: Create new privileged user account 'hadoop'? (yes/no) yes
*** Info: Please enter a password for new user hadoop.  Please be sure
*** Info: that this password matches the password rules given on your system.
*** Info: Entering no password will exit the configuration.
*** Query: Please enter the password:
*** Query: Reenter:

*** Info: User 'hadoop' has been created with password 'hadoop'.
*** Info: If you change the password, please remember also to change the
*** Info: password for the installed services which use (or will soon use)
*** Info: the 'hadoop' account.

*** Info: Also keep in mind that the user 'hadoop' needs read permissions
*** Info: on all users' relevant files for the services running as 'hadoop'.
*** Info: In particular, for the sshd server all users' .ssh/authorized_keys
*** Info: files must have appropriate permissions to allow public key
*** Info: authentication. (Re-)running ssh-user-config for each user will set
*** Info: these permissions correctly. [Similar restrictions apply, for
*** Info: instance, for .rhosts files if the rshd server is running, etc].


*** Info: The sshd service has been installed under the 'hadoop'
*** Info: account.  To start the service now, call `net start sshd' or
*** Info: `cygrunsrv -S sshd'.  Otherwise, it will start automatically
*** Info: after the next reboot.

*** Info: Host configuration finished. Have fun! 

建议按上述步骤执行，这样服务里的Cygwin ssh可以直接启动（已经自动修改好了登录用户）。另外在win7Cmd中输入net user hadoop，显示如下：

C:\Users\anjx>net user hadoop

用户名                 hadoop
全名                   Privileged server
注释
用户的注释
国家/地区代码          000 (系统默认值)
帐户启用               Yes
帐户到期               从不

上次设置密码           2012/6/27 17:45:17
密码到期               从不
密码可更改             2012/6/27 17:45:17
需要密码               Yes
用户可以更改密码       Yes

允许的工作站           All
登录脚本
用户配置文件
主目录                 D:\Cygwin\var\empty
上次登录               从不

可允许的登录小时数     All

本地组成员             *Administrators       *Users
全局组成员             *None
命令成功完成。

  而通过控制面板可以看到新增了个用户“Privileged server”。注意这个就是hadoop用户的全名，并非两个用户。

如果想多次测试，可以使用cygrunsrv -R sshd来删除当前sshd服务。另外在删除系统中的用户时，除了win7用户，还要到Cygwin/etc/passwd文件中删除掉刚才新建的用户。 

三 按quick start进行即可。

请问，你没有碰到 native library的问题吗？我在启动例子的时候就会报这个问题，而且官方文档说不支持win/cygwin/mac os x平台的。
