Please bear in mind that there are 2 different JDBC drivers in the mix.     Cloudera Hive JDBC driver is used by Hive clients to connect to HiveServer2 (HS2).  The Hive Metastore Server (HMS) uses the JDBC driver supplied by the vendor.      In any case, Hive follows the convention that database/tables names are case insensitive.
