Ivan Mitic commented on HADOOP-9043:
------------------------------------
Thanks Arpit. I am fine with failing early in winutils#symlink in case we
detect a forward slash. Seems useful for this scenario given that the symlink
creation succeeds, but the link is not working. However, I would not recommend
trying to support both forward and backward slashes in wintuils. Java is meant
to solve this problem for us, so let's just build on top of it.

> 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.
