      Dynamic endpoints must now be refactored to use CoprocessorService instead of CoprocessorProtocol. See the coprocessor package info javadoc for example. Study unit tests for examples where we migrate for old style to new. Write the mailing list if you need help because a few fellas have volunteered to help those who need to migrate.

    Description

      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.
