Chuan Liu resolved HADOOP-8674. ------------------------------- Resolution: Duplicate Duplicate of HADOOP-8694 > Create true symbolic links on Windows > ------------------------------------- > > Key: HADOOP-8674 > URL: https://issues.apache.org/jira/browse/HADOOP-8674 > Project: Hadoop Common > Issue Type: Bug > Reporter: Chuan Liu > Assignee: Chuan Liu > > 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. -- This message is automatically generated by JIRA.
