> Test case initialization order under Maven and SBT are different. Maven always creates instances of all test cases and then run them altogether.
> This fails {{ObjectHashAggregateSuite}} because the randomized test cases their registers a temporary Hive function right before creating a test case, and can be cleared while initializing other successive test cases.
> In SBT, this is fine since the created test case is executed immediately after creating the temporary function. 
> To fix this issue, we should put initialization/destruction code into {{beforeAll()}} and {{afterAll()}}.
