> Key: HIVE-22
> URL: https://issues.apache.org/jira/browse/HIVE-22
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Reporter: Joey Pan
>
> Here is what I observed, in a hive command: from ad_stat2 join ad
> on(ad_stat2.ad_id=ad.ad_id) select ad_stat2.*, ad.ad_id where
> ad_stat2.ad_clk>1000;
> In the command, 2 tables are involved, the observation is if the output
> includes all columns of left table(ad_stat2.*), then no matter what columns
> you pick for the right table, it will print out all columns of right table.
