             Summary: MasterServices - remove from coprocessor API (Discuss)
                 Key: HBASE-12260
                 URL: https://issues.apache.org/jira/browse/HBASE-12260
             Project: HBase
          Issue Type: Bug
          Components: master
            Reporter: ryan rawson
            Priority: Minor


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.
