----------------------------------------------
Summary: Remove push down expressions from FilterJoinRule and
create a new rule for it
Key: HIVE-11610
URL: https://issues.apache.org/jira/browse/HIVE-11610
Project: Hive
Issue Type: Bug
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
CALCITE-457 added pushing expressions in join conditions into projects below
the join in the FilterJoinRule, so the expression would be computed beforehand
and not in the join predicate.
While this can be an interesting feature for some projects using Calcite, it is
a different functionality and it should be a standalone independent rule. For
instance, in Hive we do not want to enable it at the moment, as it causes some
performance regressions in many test cases.
