-RE: Hive Unit Tests: Read-Only Table

Hi Namit, If I understand correctly, she wants to create a new table (Not modifying the existing tables) as part of the test setup to validate her new UDFs. Are there any guidelines on where to create new tables with different data to validate new UDFs?

You cannot change tables which are created by QTestUtil (like src).
