> Following query fails when with *Error: UNSUPPORTED_OPERATION ERROR:
> Hash-Join can not partition the inner data any further (probably due to too
> many join-key duplicates)* on TPC-H SF100 data.
> {code:sql}
> set `exec.hashjoin.enable.runtime_filter` = true;
> set `exec.hashjoin.runtime_filter.max.waiting.time` = 10000;
> set `planner.enable_broadcast_join` = false;
> select
> count(*)
> from
> lineitem l1
> where
> l1.l_discount IN (
> select
> distinct(cast(l2.l_discount as double))
> from
> lineitem l2);
> reset `exec.hashjoin.enable.runtime_filter`;
> reset `exec.hashjoin.runtime_filter.max.waiting.time`;
> reset `planner.enable_broadcast_join`;
> {code}
> The subquery contains *distinct* keyword and hence there should not be
> duplicate values.
> I suspect that the failure is caused by semijoin because the query succeeds
> when semijoin is disabled explicitly.
