Subject [jira] [Created] (HBASE-14232) Backwards compatiblity support for new MasterObserver APIs

--------------------------------------

             Summary: Backwards compatiblity support for new MasterObserver APIs
                 Key: HBASE-14232
                 URL: https://issues.apache.org/jira/browse/HBASE-14232
             Project: HBase
          Issue Type: Sub-task
            Reporter: Andrew Purtell


The group assignment changes introduce new methods to the MasterObserver interface. This is
a concern for things like Apache Phoenix. (See their IndexMasterObserver, etc.) We can handle
this by using compatibility helpers that won't attempt to invoke the new APIs on MasterObservers
that do not implement them.
