HI, @KurtYoung Thanks for your attention to this PR. Good question, the
purpose of this change is just like this JIRA's description:
I want `ProjectionTranslator # identifyFieldReferences` to guaranteed the
order of the extracted field references same as input order. using `Set` just
want to eliminate duplicate field references, and `List` also can do this, it
is no harm to keep the `ProjectionTranslator # identifyFieldReferences`
method's output order consistent with input.
If the disorder results of `ProjectionTranslator #
identifyFieldReferences` can work, then the orderly results must also work very
well, because the order is also a situation of disorder.
What to you think?
Thanks,
SunJincheng
