Description

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.
