> 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.
