Bikas Saha commented on HADOOP-9061:
------------------------------------
I agree. Redoing things like rename and length are not future proof because
folks can simply use File api's and get incorrect results. +1. Code looks good.
> Java6+Windows does not work well with symlinks

> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 1-win
> Reporter: Ivan Mitic

>
>
> We’ve seen multiple problems with file operations on symbolic links on Java6
> on Windows. Specifically:
> - File#length returns zero on symbolic links
> - File#renameTo renames the target, not the symlink
> Problematic scenarios are mainly related to symlinks created for dist cache.
> Java7 does not have above problems.
