> As discussed in HADOOP-6536, FileUtil#fullyDelete should not delete the
> contents of the sym-linked directory when we pass a symlink parameter.
> Currently we try to delete the resource first by calling deleteImpl, and if
> deleteImpl is failed, we regard it as non-empty directory and remove all its
> contents and then itself. This logic behaves wrong when local file system
> cannot delete symlink to a directory because of faulty disk, local system's
> error, etc. When we cannot delete it in the first time, hadoop will try to
> remove all the contents of the directory it pointed to and leave an empty dir.
> So, we should add an isSymlink checking before we call fullyDeleteContents to
> prevent such behavior.
