Gergo Repas commented on MAPREDUCE-7030:
----------------------------------------
Thanks [~miklos.szeg...@cloudera.com] for the patch. Couple of comments:
# Regarding detecting symlinks that points to the same directory: it can be
done via the nio API, for example:
{code}
Path jarParent = jarPath.getParent();
if (jarParent.equals(jarParent.resolve(linkString).getParent().normalize())) {
{code}
This would also cover ./dir/../dir/destination, ../parentdir/destination type
links.
# Currently a NotLinkException is thrown for non-symlink files, this can be
avoided be changing the {{if (ignoreSymlink)}} condition to {{if (ignoreSymlink
&& Files.isSymbolicLink(jar.toPath()))}}
> Uploader tool should ignore symlinks to the same directory
