Peter Vary commented on HIVE-17542:
-----------------------------------

[~stakiar]: Is it worth to add the query results to the tests too, or these are covered by
other tests? Otherwise looks good to me.

Thanks,
Peter

> The {{CombineEquivalentWorkResolver}} is run by default. We should make it configurable
so that users can disable it in case there are any issues. We can enable it by default to
preserve backwards compatibility.
