> HADOOP-2808 introduced a new signature for the copy method that takes an
> overwrite flag.
> Before this patch the behavior, for the pre-existing copy method, was that if

> behavior, for the pre-existing copy method, is that if the destination exists
> it is overwritten.
> The behavior of the pre-existing copy method should not have changed.
