Actually the other intention was let test fail when "includeHeaders" is set to "true", as we suspected from #22282 (comment), but turns out it doesn't break even the option is set to true. It's because of the mechanism how Luckily it doesn't let query crash, but it would be ideal to do type check and avoid the possibility of crashing in runtime - SPARK-27237 (#24173) has been proposed to address this. |
