Can't partition by expression when columns are explicitly specified in the CTAS column list

    Details

      Description

      Query below throws an error:

      create table test(x1, x2) partition by (x1) as 
      select    sum(a1),  b1 
      from       t1 
      group by  b1;
      
      0: jdbc:drill:schema=dfs> create table test(x1, x2) partition by (x1) as select sum(a1), b1 from t1 group by b1;
      Error: SYSTEM ERROR: IllegalArgumentException: partition col x1 could not be resolved in table's column lists!
      [Error Id: ab5624e8-e4dd-4752-95af-8bc2eef5d056 on atsqa4-133.qa.lab:31010] (state=,code=0)
      

      When column aliases are used, it works:

      0: jdbc:drill:schema=dfs> create table test partition by (x1) as select sum(a1) x1, b1 x2 from t1 group by b1;
