> Hive is case insensitive wrt db/table names. These gets normalized to lower
> case for SQL processing.
> When HiveEndPoint is created it uses db.table strings as is, and they end up
> propagated this way to transaction metadata tables in the metastore via lock
> acquisition. This makes them look like different tables in Cleaner and lock
> manager.
