Description

TajoMaster mainly has three roles:

• query coordination (including query scheduler)
• cluster resource management
• client endpoint

TajoMasterProtocol has played a role of query coordinator. But, its name is not expressive in terms of its purpose. This patch proposes the rename from TajoMasterProtocol to QueryCoordinatorProtocol.
