Ivan Mitic commented on HADOOP-9043:
------------------------------------
bq. Forward paths in the source already appear to be rejected. Do you see
otherwise?
Do you see this rejected by winutils? Please add a test anyways to make sure
this is the case.

> In general, the winutils symlink command rejects attempts to create symlinks
> targeting a destination file that does not exist. However, if given a
> symlink destination with forward slashes pointing at a file that does exist,
> then it creates the symlink with the forward slashes, and then attempts to
> open the file through the symlink will fail.
