Description

As part of the work over in HBASE-15638, "Shade Protobufs", I could not but help noticing that of the seven or eight Coprocessor Endpoints bundled with hbase, half should have been converted to be core long time again. In fact, some of these core CPEPs are no longer viable as CPEPs, if they ever were, given how intertwined with core they are.

For example, MultiRowMutation, the nice CPEP that allows us do cross-row transactions used natively amending hbase:meta, has much of its facility baked into core without which it could not run. In an exercise, I was able to convert this one over without having to alter public APIs in Table or Admin.

Auth, as pointed out by mbertozzi, is not a Coprocessor Endpoint though it is cast as one invoked natively by RPC.

VisibilityLabels is a CPEP but core types – Query and Mutation – actually depend on VisibiltyLabel related classes.

SecureBulkLoad is not in any violation being a CPEP provided to add API ahead-of-time since properly deprecated and already integrated to core but I mention it here for completeness sake.
