Subject [jira] [Commented] (HBASE-19007) Align Services Interfaces in Master and RegionServer
Date Tue, 17 Oct 2017 15:32:00 GMT

Guanghao Zhang commented on HBASE-19007:
----------------------------------------

Sorry to join this discussion late. IMO, use Server to expose to CP is not better than use
CPRSS/CPMS. It is still easily misused in the future... We need find a better way for this.
bq. I'd suggest that anything and everything that needs to be exposed to CP should be a method
in some env. Even if we want to expose a full set of functions, which are already in an internal
interface, let's not expose the interface. Instead, let's make wrapper functions in the CpEnv.
[~appy]'s suggestion sounds good. What you guys think?

> 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.
