------------------------------------
Fix Version/s: Impala 4.4.1
Resolution: Fixed
> 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
> Fix For: Impala 4.4.1
>
>
> 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().
> In particular, the following query causes IllegalStateException
> {code}
> USE functional;
> SELECT alt.int_col, alt.string_col
> FROM alltypes alt
> INNER JOIN (
> SELECT int_col,
> concat('20', substring(date_string_col, 7, 2), '-',
> substring(date_string_col, 4, 2), '-', substring(date_string_col, 1, 2), '
> 00:00:00') ts
> FROM alltypesaggnonulls GROUP BY int_col, date_string_col
> ) altann ON altann.ts = from_unixtime(alt.id, 'yyyy-MM-dd HH:mm:ss');
> {code}
