> 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.

> set `exec.hashjoin.runtime_filter.max.waiting.time` = 10000;
> set `planner.enable_broadcast_join` = false;

>  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.
