>                 URL: https://issues.apache.org/jira/browse/DRILL-3943
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Query Planning & Optimization
>            Reporter: Sean Hsuan-Yi Chu
>            Assignee: Sean Hsuan-Yi Chu
>             Fix For: 1.3.0

> For a query such as:
> {code}
> SELECT count(DISTINCT employee_id) as col1,
> count((to_number(date_diff(now(), cast(birth_date AS date)),'####'))) as col2
> FROM cp.`employee.json`
> {code}
> cannot plan exception will be thrown because ExpressionReductionRule does not properly simply the call "now()".
> This issue is similar to DRILL-2808, but that one focuses on error message.
