Zoltan Haindrich commented on HIVE-18445:
-----------------------------------------
I was looking into whether this feature works for producing test cases for
reoptimization...and I've probably just bumped into the reason this test have
changed after HIVE-13567:
[https://github.com/apache/hive/blob/6938fcabf0944817fed8241c48b57fb3f5d98c69/ql/src/java/org/apache/hadoop/hive/ql/optimizer/physical/LocalMapJoinProcFactory.java#L133
which is a feature introduced in HIVE-1830
so probably setting {{hive.mapjoin.followby.gby.localtask.max.memory.usage}} to
some low value would probably re-introduce the backuptasks
> qtests: auto_join25.q fails permanently
