Sean Hsuan-Yi Chu commented on DRILL-2808:
------------------------------------------
In this special case,
{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}
it would cause CannotPlanException.
This is a particularly important case.
