> The CoprocessorProtocol mechanism for registering and calling coprocessor endpoints has been supplanted by protocol buffer based service registrations in HBASE-5448.  This means the Writable-based CoprocessorProtocol mechanism will need to be removed at some point.
> In discussion on the dev list, general consensus was that it is better to remove the CoprocessorProtocol mechanism completely in 0.96, where other backwards-incompatible changes are being made, and before it is adopted by more clients:

> This is an umbrella issue to track what changes are required to completely remove the CoprocessorProtocol support.
