-------------------------------------
Summary: Potential 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
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().
