Review Comment:
Thanks, I see you.
Actually, I don't know why primiteive array is not supported. It's legacy
code I have no knowledge.
According to my insight and test with Hive's qtest. it should be supported.
I think the validation can be droped.
But currently, I would like to keep it and then see what will happen.
