             Summary: Insert + orderby + limit does not need additional RS for limiting rows
                 Key: HIVE-5062
                 URL: https://issues.apache.org/jira/browse/HIVE-5062
             Project: Hive

            Reporter: Navis
            Assignee: Navis

The query,

{noformat}
insert overwrite table dummy select * from src order by key limit 10;
{noformat}

runs two MR but single MR is enough.
