    ```UndefinedDatabaseException``` also should be handled. 
    In addition, ```DuplicatePartitionException``` is missed at 
CatalogServer.addPartitions(). It would be great if you add it.

> * Rename UnImplementedException to NotImplementedException.
> * Replace CatalogException by TajoException
> * Move almost TajoException/TajoRunException in tajo-core into tajo-common
> * Remove CatalogException and CatalogExceptionUtil
> * Add throwable exception to all APIs in TajoClient, QueryClient, 
> CatalogService, and CatalogAdminClient.
> * Refine all client implementations to throw received exception exactly.
> * Add negative unit tests for all APIs of them
> * Refine Client API v2 to handle exceptional cases like query failed, and 
> killed.
> * Add query fail and kill tests for Client v2
