Yi Tian commented on SPARK-3688:
--------------------------------
As we know, the hive support complex colunm datatype like struct.
So it is hard to resolve a reference like a.b.c
I think we should add some judgements on the datatype attributes, like:
{quote}
option.dataType.isInstanceOf[StructType]
{quote}
> LogicalPlan can't resolve column correctlly
