Review request for hive.
Summary
-------
Insert Overwrite table db.tname fails if partition already exists.
For example-
insert overwrite table db.tname PARTITION(part='p') select .. from t2 where
part='p'; fails if partition 'p' already exists.
Internal of the code not consider the database name of the table and it is
continued with the default database.
Changed the code like if table contains the database name called the alter
partition using the dbname and tablename.
This addresses bug HIVE-2617.
