> Often times when we use the FileVisitor, we don't need to collect all the files in the snapshot, but really just a subset. In the current implementation, we still look at all the files in all the subfolders in the the snapshot, which puts extra stress on an already stressed namenode.
> A simple implementation can just use a simple PathFilter to determine which files/directories should be passed to the FileVisitor.
