> The following query returns, incorrectly, an empty result set:
> {noformat}
> 0: jdbc:drill:zk=local> SELECT employee_id, position_id, salary, SUM(salary) OVER() FROM cp.`employee.json` LIMIT 1000;
> +--------------+--------------+---------+---------+
> | employee_id  | position_id  | salary  | EXPR$3  |
> +--------------+--------------+---------+---------+
> +--------------+--------------+---------+---------+
> No rows selected (0.287 seconds)
> {noformat}
> DRILL-1862 is required otherwise such queries won't plan at all.
> The problem is caused by WindowFrameRecordBatch.buildSchema() which assumes the very first batch to be an empty batch that only contains the schema, which is not the case when using OVER()
