------------------------------------
+1.
I run the regression suite in Drill, and did not see any issue.
> Remove push down expressions from FilterJoinRule and create a new rule for it

> Project: Calcite
> 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.
