> It would be very useful for us to be able to wrap the filesystems
> encapsulated by HFileSystem with other FilterFileSystems. This allows for
> more detailed logging of the operations to the DFS. Internally, the data
> logged from this method has allowed us to show application engineers where
> there schemas are inefficient and inducing too much IO. This patch will just
> allow the filesystem to be pluggable.
