> Project: Hive
> Issue Type: Improvement

> For instance, in perf driver CBO query 74, there are several filters that
> could be simplified further:
> {code}
> HiveFilter(condition=[AND(=($1, 1999), IN($1, 1998, 1999))])
> {code}
> This may lead to incorrect estimates and leads to unnecessary execution time.
