> The following highlighted line seems to be incorrect in the test suite:
> [https://github.com/apache/hive/blob/master/ql/src/test/results/clientpositive/perf/tez/cbo_query95.q.out#L89]
> Note that the project takes all the columns from the table scan, yet it only needs a couple of them.
> I did some very small debugging on this. When I removed the applyJoinOrderingTransform here: [https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/parse/CalcitePlanner.java#L1897]
> ... the problem goes away. So presumably one of the rules in there is causing the problem.
> Here is a slightly simplified version of the query which has the same problem (using the same tpc-ds database):
> explain cbo with ws_wh as
> (select ws1.ws_order_number
> from web_sales ws1,web_returns wr2
> where ws1.ws_order_number = wr2.wr_order_number)
> select
> ws_order_number
> from
> web_sales ws1
> where
> ws1.ws_order_number in (select wr_order_number
> from web_returns,ws_wh
> where wr_order_number = ws_wh.ws_order_number)
