Cheng Lian updated SPARK-18338:
-------------------------------
Description:
Test case initialization order under Maven and SBT are different. Maven always
creates instances of all test cases and then run them all together.
This fails {{ObjectHashAggregateSuite}} because the randomized test cases there
register 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()}}.

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

In SBT, this is fine since the created test case is executed immediately after
