------------------------------------------
Updating this to major because portability is a pain in the ass.

> HADOOP-9652 introduces a new class which shells out to stat(1) because of the lack of lstat(2) in Java 6. Java 7 has support for reading symlink targets via {{Files#readSymbolicLink}}.
> When Hadoop drops Java 6 support, let's use this more portable method instead.
> See:
