> -------------------------------------------------------------
>
>                 Key: HIVE-24154
>                 URL: https://issues.apache.org/jira/browse/HIVE-24154
>             Project: Hive
>          Issue Type: Improvement
>          Components: CBO
>            Reporter: Jesus Camacho Rodriguez
>            Assignee: Jesus Camacho Rodriguez
>            Priority: Minor
>
> 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.
