> See the existent test 'NestLoopJoinHintTest#testJoinHintWithJoinHintInCorrelateAndWithAgg', the test plan is

> HashJoin(joinType=[LeftSemiJoin], where=[=(a1, EXPR$0)], select=[a1, b1], build=[right], tryDistinctBuildRow=[true])

> +- Exchange(distribution=[hash[EXPR$0]])
> +- LocalHashAggregate(groupBy=[EXPR$0], select=[EXPR$0])
> +- Calc(select=[EXPR$0])
> +- HashAggregate(isMerge=[true], groupBy=[a1], select=[a1, Final_COUNT(count$0) AS EXPR$0])
> +- Exchange(distribution=[hash[a1]])
> +- LocalHashAggregate(groupBy=[a1], select=[a1, Partial_COUNT(a2) AS count$0])
> +- NestedLoopJoin(joinType=[InnerJoin], where=[=(a2, a1)], select=[a2, a1], build=[right])
> :- TableSourceScan(table=[[default_catalog, default_database, T2, project=[a2], metadata=[]]], fields=[a2], hints=[[[ALIAS options:[T2]]]])
> +- Exchange(distribution=[broadcast])
> +- TableSourceScan(table=[[default_catalog, default_database, T1, project=[a1], metadata=[]]], fields=[a1], hints=[[[ALIAS options:[T1]]]]) {code}
> but the NestedLoopJoin should broadcase left side.
