[jira] [Commented] (HADOOP-9483) winutils support for readlink
command
[ https://issues.apache.org/jira/browse/HADOOP-9483?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13635923#comment-13635923 ]
Chuan Liu commented on HADOOP-9483:
-----------------------------------
MSDN says:
{quote}
A final path is the path that is returned when a path is fully resolved. For example, for a symbolic link named "C:\tmp\mydir" that points to "D:\yourdir", the final path would be "D:\yourdir".
The string that is returned by this function uses the \\?\ syntax.
{quote}
So I think it will be full path prefixed with "\\?\".

> The current codebase relies on the Unix readlink command to determine the target of a symlink on the local file system. winutils currently does not support this functionality on Windows. Adding the command to winutils will prevent the need to use GnuWin32 or Cygwin for readlink support.
