Andrew Purtell updated HBASE-3256:
----------------------------------
Description:
Implement a coprocessor host for HMaster. Hook observers into administrative
operations performed on tables: create, alter, assignment, load balance, and
allow observers to modify base master behavior. Support automatic loading of
coprocessor implementation.
Consider refactoring the master coprocessor host and regionserver coprocessor
host into a common base class.

Coprocessors: Add MasterObserver interface and refactor observers onto a common
