> 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.
