> TezLocalCacheManager tries to generate symlinks to files that it puts in the
> local cache, but the code that it uses to construct the path names is not
> safe on Windows and causes bad file names to be constructed when run in a
> Windows environment. On Windows, a path like file:/c:/path/to/my/file should
> be legal and transform to c:\path\to\my\file, but with the invalid construct,
> it turns into the illegal value /c:/path/to/my/file instead.
> In TezLocalCacheManager, there is code that does
> {code}
> private boolean createSymlink(Path target, Path link) throws IOException {
> LOG.info("Creating symlink: {} <- {}", target, link);
> String targetPath = target.toUri().getPath();
> String linkPath = link.toUri().getPath();
> {code}
> It looks like there are several other places in the Tez code that also use
> the Path.toUri().getPath() construct that probably also need to be fixed in
> order to work correctly on Windows.
> The construct Path.toUri().getPath() doesn't handle windows directories
> correctly. The Java File class understands how to do this correctly, so this
> should really be replaced by
> {code}
> private boolean createSymlink(Path target, Path link) throws IOException {
> LOG.info("Creating symlink: {} <- {}", target, link);
> String targetPath = new File(target.toUri()).getCanonicalPath();
> String linkPath = new File(link.toUri()).getCanonicalPath();
> {code}
> {code}
