Description

HIVE-16723 gives the ability to have a custom MetastoreSchemaInfo implementation to manage schema upgrades and initialization if needed. In order to make HiveSchemaTool completely agnostic it should depend on IMetastoreSchemaInfo implementation which is configured to get the metastore schema version information from the database. It should also not assume the scripts directory and hardcode it itself. It would rather ask MetastoreSchemaInfo class to get the metastore scripts directory.
