> Investigating a failed query:
> {code}
> set hive.cbo.enable=false;
> set hive.orderby.position.alias=true;
> select distinct age from student order by 1 desc limit 20;
> {code}
> The query does not sort the output correctly when cbo is disabled/inactivated. I found
two issues:
> 1. "order by position" query is broken by HIVE-16774
> 2. In particular, select distinct query never work for "order by position" query
