Description

HiveCatalogStore can be a catalog store driver in the current implementation. It has some problems:

• The data warehouse directories of between Tajo and Hive are different to each other. This can cause the directory mismatch problem.
• HiveCatalogStore does not fully support All Tajo features.

If we move it to a linked metadata provider, we could resolve the directory mismatch problem with the tablespace feature. We could also use Hive meta store while All Tajo features are available.
