okumin commented on HIVE-27858:
-------------------------------
I assume [~jfs] tested it with `hive.cbo.fallback.strategy=NEVER`. As far as I
investigated, HIVE-24167 makes CBO fail but the non-CBO part will not likely
fail. Please correct us if our assumption is wrong.
> OOM happens when selecting many columns and JOIN.
