             Summary: CannotPlanException caused by ExpressionReduction rule
                 Key: DRILL-3943
                 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.
