> Assignee: Vineet Garg
> Priority: Major
> Attachments: HIVE-21340.1.patch, HIVE-21340.2.patch

> {code}
> explain cbo
> with ss as
> (select count(1), ss_item_sk, ss_ticket_number from
> store_sales group by ss_item_sk, ss_ticket_number
> having count(1) > 1)
> select count(1) from item where i_item_sk IN (select ss_item_sk from ss);
> {code}
> Notice the {{HiveProject(ss_item_sk=[$0], ss_ticket_number=[$1], $f2=[$2])}}
> Only ss_item_sk is relevant for the HiveSemiJoin

> CBO PLAN:
> HiveAggregate(group=[{}], agg#0=[count()])
> HiveSemiJoin(condition=[=($0, $1)], joinType=[inner])
> HiveProject(i_item_sk=[$0])
> HiveFilter(condition=[IS NOT NULL($0)])
