Arpit Agarwal updated HADOOP-9483:
----------------------------------
Attachment: HADOOP-9483.patch
Attaching a patch for "winutils readlink".
I used the FSCTL to get the closest behavior to POSIX readlink.
The initial call to GetFileInformationByHandle is not required as the results
of the FSCTL are sufficient to distinguish between sym links and other file
types.
Chris's initial research was very helpful.

> 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.
