Amareshwari Sriramadasu commented on HIVE-1657:
-----------------------------------------------
The problem is in generating "select \*" plan. Currently, select \* looks at
the row resolver of the previous operator and adds all the columns to the
output. Instead, it should add them in the order of aliases/table-names
specified in the query.
> join results are displayed wrongly for some complex joins

> URL: https://issues.apache.org/jira/browse/HIVE-1657
> Project: Hive
> Issue Type: Bug
> Reporter: Amareshwari Sriramadasu
>
> Noticed that the output of the join is displayed wrongly for queries
> involving more than one table and mixture of left and outer joins, with
> different join conditions.
> For ex: SELECT * from T1 a RIGHT OUTER JOIN T2 b ON (a.value=b.value) LEFT
> OUTER JOIN T3 c ON (b.key=c.key);
> displays the table T2 first, then T1 and T3.
