["Yi Tian (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-3688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14147520#comment-14147520 ] 

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}
