--------------------------------------
Summary: Review Predicate arguments for impact of CNF rewrites
Key: IMPALA-11770
URL: https://issues.apache.org/jira/browse/IMPALA-11770
Project: IMPALA
Issue Type: Bug
Affects Versions: Impala 4.1.0
Reporter: Michael Smith
CNF rewrites can modify predicate children. We've found at least one instance -
IMPALA-11766 - where a predicate child expression wasn't cloned, so
modification messed up other use of the expression.
We should review CNF rewrite's impact on predicate child expressions and
whether there are other places expressions need to be cloned before passing
them in.
