stack commented on HBASE-19007:
-------------------------------

On @appy comments...

bq.  Even if the original author designed these for CP only... 

No. MS and RSS were for internal, mock/test use originally. Only Region 
Interface to my knowledge was for CP only.

bq. What do you say...

Yeah. Before you commented, I was trying to work it so CPs got everything from 
CpEnv (no Server exposed). Code actually looks better. Expectations are better 
managed too; i.e. if you need anything, get it from the environment. But see my 
problem above. Raw CpEnv base Interface is somehow to produce access to the 
'servers' ZKW. A few CPs depend on this working. Others want access to 
HRegionServer....  

Thanks [~appy]

> HBASE-18183 adds a CoprocessorRegionServerService to give a view on 
> RegionServiceServices that is safe to expose to Coprocessors.
> On the Master-side, MasterServices becomes an Interface for exposing to 
> Coprocessors.
> We need to align the two.
