> Single sourced multi (insert) query is very useful for various ETL processes but it does not allow subqueries included. For example, 
> {noformat}
> explain from src 
> insert overwrite table x1 select * from (select distinct key,value) b order by key
> insert overwrite table x2 select * from (select distinct key,value) c order by value;
> {noformat}
