Chris Nauroth commented on HADOOP-9043:
---------------------------------------
Tightening up the validation is great, but we still have the problem that
{{TestLocalFSFileContextSymlink}} passes on Linux but fails on Windows. The
current state of the discussion here is that winutils will enforce validation
rules to reject creation of invalid/dangling symlinks. Since this diverges
intentionally from the Linux behavior, do we want to update
{{TestLocalFSFileContextSymlink}} to add {{assumeTrue(!Shell.WINDOWS)}} on the
invalid tests?
> 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.
