Ivan Mitic commented on HADOOP-9043:
------------------------------------
Thanks Arpit, this is good. A few comments, mainly minor:
1. Can we do the same check for both source and target?
2. Please log additional information about the problem to stderr. This will
help see what went wrong on the Java side.
3. Please add a unittest to TestWinUtils that validates the fix
> winutils can create unusable symlinks

> 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.
