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

I wrote the above comment is just for the purpose to suggest each partition should have one
record in catalog. :)

> Table partitioning gives many facilities to maintain large tables. First of all, it enables
the data management system to prune many input data which are actually not necessary. In addition,
it gives the system more optimization  opportunities  that exploit the physical layouts.
> Basically, Tajo should follow the RDBMS-style partitioning system, including range, list,
hash, and so on. In order to keep Hive compatibility, we need to add Hive partition type that
does not exists in existing DBMS systems.
