      Description

      Currently, there is no method to update existing table information at CatalogStore. So, if user execute an insert query, tajo drop a table and then tajo create a table. It doesn't matter to tajo own CatalogStore like DerbyStore, MySQLStore. But it is a critical issue to HCatalogStore. if tajo drop a existing partitioned table, users will lose existing partition informations. As a result, they should repair table partition against their will. As you know, hive msck command can affect hive metastore performance.
