> I hit an IOBE for TestTpchDistributed Q4, when I tried to enable an optimizer
> rule. Then, I simplified Q4 to the following, and still re-produce the same
> IOBE.
> {code}
> select
> o.o_orderpriority
> from
> cp.`tpch/orders.parquet` o
> where
> exists (
> select
> *
> from
> cp.`tpch/lineitem.parquet` l
> where
> l.l_orderkey = o.o_orderkey
> )
> ;

> The physical plan seems to be correct, after enabling the new rule. Actually,
> if I disable HashJoin, and use merge join for the query, it works fine. So,
> seems the IOBE exposes some bug in HashJoin.
> To re-produce this issue, two options:
> 1 ) - Modify DrillRuleSets.java, remove the comment before SwapJoinRule
> - alter session set `planner.slice_target` = 10;
> - run the query
>
> 2) use the attached physical plan in json file, and use "submitplan" to
> submit the physical plan.
> For comparison, I also attached the physical plan when disabling hashjoin
> (use merge join), and the explain plan at physical operator level.
