stack created HBASE-16757:
-----------------------------
Summary: Integrate functionality currently done up as Coprocessor
Endpoints into core.
Key: HBASE-16757
URL: https://issues.apache.org/jira/browse/HBASE-16757
Project: HBase
Issue Type: Task
Components: Coprocessors
Reporter: stack
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.
