> In branch-1-win, we currently copy files for symbolic links in Hadoop on 
> Windows. We have talked to [~davidlao] who made the original fix, and did 
> some investigation on Windows. Windows began to support symbolic links 
> (symlinks) since Vista/Server 2008. The original reason to copy files instead 
> of creating actual symlinks is that only Administrators has the privilege to 
> create symlinks on Windows _by default_. After talking to NTFS folks, we knew 
> the reason for that is mostly due to security, and this default behavior may 
> not be changed in near future. Though this behavior can be changed via  the 
> Local Security Policy management console, i.e. secpol.msc, under Security 
> Settings\Local Policies\User Rights Assignment\Create symbolic links.
>  
> In Hadoop, symlinks is mostly used to for DistributedCache and attempted 
> logs. We felt the usages are important enough for us to provide true symlinks 
> support, and users need to have the symlink creation privilege enabled on 
> Windows to use Hadoop.
> This JIRA is created to tracking symlink support on Windows.
