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

+1, JaeHwa.
I'm glad for you to start to implement HCatalogStore.
And, I always welcome to discuss the Catalog Federation issue.

> I designed Tajo to use Hive metastore with HCatalog.
> In this case, Tajo has to have an interface to connect to HCatalog.
> And I think that this connect is very useful to connect to another catalogs as follows:
>  some different Hive catalogs, HBase catalogs
> So, I named this interface as CatalogDriver. It will has some properties as follows:
> - catalog namespace name
> - catalog URI
> - catalog driver class
