>                 URL: https://issues.apache.org/jira/browse/IMPALA-7254
>             Project: IMPALA
>          Issue Type: Bug
>          Components: Frontend
>    Affects Versions: Impala 3.0

> The following query returns an error:
> {code:java}
> select cast(2 as decimal(38,37)) in (cast(3 as decimal(38,1)), cast(2 as double)){code}
> However, this query succeeds and returns true:
> {code:java}
> select cast(2 as decimal(38,37)) in (cast(2 as double), cast(3 as decimal(38,1))){code}
> The only difference is that the elements in the list are in a different order. This behavior seems strange. Perhaps we should sort the elements before analyzing?
