Deneche A. Hakim commented on DRILL-3679:
-----------------------------------------
Looking at the plan, this looks similar to DRILL-3680: the Project operator
couldn't find {{w0$o00}} because both window functions output to the same field
{{w0$o0}}
{noformat}
explain plan for select rnum, ntile(4) over(order by position_id) from (select
position_id, row_number() over(order by position_id) as rnum from
cp.`employee.json`);
