> URL: https://issues.apache.org/jira/browse/HIVE-14021
> Project: Hive
> Issue Type: Improvement
> Components: CBO
> Affects Versions: 2.1.0, 2.2.0

> When converting to conjunctive normal form (CNF), fail if the expression
> exceeds a threshold. CNF can explode exponentially in the size of the input
> expression, but rarely does so in practice. Add a maxNodeCount parameter to
> RexUtil.toCnf and throw or return null if it is exceeded.
