----------------------------

             Summary: CTAS queries for window functions creating files without column names
                 Key: DRILL-5109
                 URL: https://issues.apache.org/jira/browse/DRILL-5109
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill, Storage - Writer
    Affects Versions: 1.8.0, 1.9.0
            Reporter: Nitin


Following query when executed,0: jdbc:drill:zk=local> create table dfs.tmp.`/tmp/t` as
select cast(employee_id as double) employee_id, cast(department_id as double) department_id,cast(salary
as double) salary,DENSE_RANK( ) over( partition by cast(department_id as double)  order by
cast(salary as double) asc  nulls first  )  dummy_DENSE_RANK from cp.`employee.json`0: jdbc:drill:zk=local>
select * from dfs.tmp.`/tmp/t` limit 5;+------+------+----------+-----+|  $0  |  $1  |   
$2    | $3  |+------+------+----------+-----+| 1.0  | 1.0  | 80000.0  | 4   || 2.0  | 1.0
 | 40000.0  | 3   || 4.0  | 1.0  | 40000.0  | 3   || 5.0  | 1.0  | 35000.0  | 2   || 6.0 
| 2.0  | 25000.0  | 4   |+------+------+----------+-----+it should have had the proper column
names. even from parquet schema it comes as bash-3.2$ java -jar parquet-tools-1.6.0rc4.jar
schema /tmp/tmp/t/0_0_0.parquet message root {  optional double $0;  optional double $1; 
optional double $2;  required int64 $3;}But when we add order by clause in query it is adding
column names looks like an issue with storage writer. This is true for all cases whichever
file format we choose to store as for CTAS
