> I have been hitting this issue while submitting patches to test HIVE-17432.
> Basically, the order on which the rewriting might create the children of AND
> operations is not deterministic. Thus, tests might fail because the created
> golden file is not the same, thought the test should pass because they just
> simply do not follow same order:
> {code}
> predicate: ((d_year >= 1992) and (d_year <= 1997) and ((c_city = 'UNITED
> KI1') or (c_city = 'UNITED KI5')) and ((s_city = 'UNITED KI1') or (s_city =
> 'UNITED KI5'))) (type: boolean)
> {code}
> {code}
> predicate: ((d_year <= 1997) and (d_year >= 1992) and ((c_city = 'UNITED
> KI1') or (c_city = 'UNITED KI5')) and ((s_city = 'UNITED KI1') or (s_city =
> 'UNITED KI5'))) (type: boolean)
> {code}
> This patches fixes the issue by sorting the children of some expressions
> (currently AND and OR children) when we run explain plan and we are running
> in test mode.
