> {{MetaStoreSchemaInfo}} class is used by Schema tool to get the schema
> version information. In addition to that schema tool invokes its init and
> upgrade methods to initialize and upgrade the metastore schema. It is
> possible that there are minor schema changes in the metastore schema which
> users have to maintain manually. We can potentially enhance schema tool to
> use a custom MetaStoreSchemaInfo implementation which can be plugged in based
> on configuration and schematool could run these customizations while running
> the upgrade and init scripts.
