Gunther Hagleitner commented on HIVE-5690:
------------------------------------------
[~navis] - since you marked this an improvement not a fix, I've set the target
0.15.0, not 0.14.0. Is that ok with you?

> 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}
