> An existing Hive metastore upgrade test is running on Hive jenkins. However,
> these scripts do test only database schema upgrade, not data validation
> between upgrades.
> We should validate data between metastore version upgrades. Using data
> validation, we may ensure that data won't be damaged, or corrupted when
> upgrading the Hive metastore.
