Review Comment:
> The purpose of q72 is to test vendors join reordering rules, and that
isn't really very relevant to Spark or Comet since Spark queries typically
don't have access to statistics.
Btw, Spark has the capacity to do join reordering if statistics are
available but it relies on enabling CBO features which are disabled by default.
