[jira] [Created] (TAJO-1943) Refactor HiveCatalogStore to be a LinkedMetaDataProvider.

             Summary: Refactor HiveCatalogStore to be a LinkedMetaDataProvider.
                 Key: TAJO-1943
                 URL: https://issues.apache.org/jira/browse/TAJO-1943
             Project: Tajo
          Issue Type: Sub-task
          Components: Catalog
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi


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.
