Xuefu Zhang commented on PIG-4276:
----------------------------------
Actually if Pig semantics doesn't guarantee an order, the test shouldn't expect
such an order just because of certain execution happens to provides that. Thus,
I'd favor doing sort-before-comparison to validate test output when order is
not deterministic. This is exactly what Hive on Spark is doing.
