>             Project: Calcite
>          Issue Type: Bug
>          Components: druid
>            Reporter: slim bouguerra

>
> The druid calcite adapter throw an exception when an IN filter is used.
> This happens only in hive because in calcite project the IN filter is 
> transformed to OR automatically. 
> Since this rule does not kick in HIVE and it is better to use the native IN 
> filter from druid instead having huge number of OR clauses i will send a 
> patch that adds the IN filter.
