Thank you for diving into this and the excellent descriptions of the
problem. I left comments on the first review. I think I could be convinced
that it's correct with a couple more tests.
I hope to get to the second review soon. I think it requires me to
understand the conjunct assignment in a bit
After examining more codes, I have some updates for these two bugs:
- IMPALA-8386 -
>Predicates inferred by only "alias predicates" should not be created. They
will definitely introduce identity predicates. Although we filter them out
in SingleNodePlanner#m
In case you hit an error like this when building Impala from the HEAD,
update Impala-lzo repo by pulling it from the master.
