Moved this out of the data loading framework because it is kind of a special case. I will consider how we can update the framework to address mixed format tables.

-- Create and load tables that depend upon data in the hive test-warehouse already existing

-- Load a mixed-format table. Hive behaves oddly when mixing formats,
|
|
-- but the following incantation ensures that the result is a
|
|
-- three-partition table. First is text format, second is sequence
|
|
-- file, third is RC file. Must be called after test-warehouse is
|
|
-- successfully populated
