Description

Hive was only recently changed to allow "drop table dbname.tabname". However DDLTask.dropTable() is still using an older version of Hive.getPartitionNames(), which only took in a single string for the table name, rather than the database and table names. As a result Hive is filling in the current database name as the dbname during the listPartitions call to the MetaStore.
It also appears that on the Hive Metastore side, in the non-auth path there is no validation to check that the dbname.tablename actually exists - this call simply returns back an empty list of partitions, which causes the table to be dropped without checking any of the partition information. I will open a separate issue for this one.
