> Bug when comparing ExprSubstitutionMap.size()
> ---------------------------------------------
>
> Key: IMPALA-13270
> URL: https://issues.apache.org/jira/browse/IMPALA-13270
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 4.5.0
> Reporter: Riza Suminto
> Assignee: Michael Smith
> Priority: Critical
>
> IMPALA-12800 implements deduplication in ExprSubstitutionMap. It is possible
> that ExprSubstitutionMap.size() will return different value after
> IMPALA-12800. We need to revisit ExprSubstitutionMap.size() calls, especially
> within Precondition such as in RuntimeFilterGenerator.computeTargetExpr() and
> ExprSubstitutionMap.trim().
