> The following query returns wrong results:
> {noformat}
> 0: jdbc:drill:> select sum(1) over w sum1, sum(5) over w sum5 from
> cp.`employee.json` where position_id = 2 window w as (partition by
> position_id);

> {noformat}
> 00-00 Screen
> 00-01 Project(sum1=[$0], sum5=[$1])
> 00-02 Project(sum1=[$0], sum5=[$1])

> 00-04 Window(window#0=[window(partition {0} order by [] range
> between UNBOUNDED PRECEDING and UNBOUNDED FOLLOWING aggs [SUM($1), SUM($2)])])
> 00-05 SelectionVectorRemover
> 00-06 Sort(sort0=[$0], dir0=[ASC])
