stack commented on HBASE-12260:
-------------------------------

.013 fix tests (except one I can't figure that comes of our using mocks over HMaster than over RegionServer around the crptic wal splitting engine). Lets see what hadoopqa says. Will look at rb in meantime. I think patch ready to go. Can address the TODOs above in follow-ons.

> A major issue with MasterServices is the MasterCoprocessorEnvironment exposes this class even though MasterServices is tagged with @InterfaceAudience.Private
> This means that the entire internals of the HMaster is essentially part of the coprocessor API.  Many of the classes returned by the MasterServices API are highly internal, extremely powerful, and subject to constant change.  
> Perhaps a new API to replace MasterServices that is use-case focused, and justified based on real world co-processors would suit things better.
