Are your test scenario is like?
```Scala
withTable("t", "tabNullType") {
val client =
spark.sharedState.externalCatalog.asInstanceOf[HiveExternalCatalog].client
client.runSqlHive("CREATE TABLE t (t1 int)")
client.runSqlHive("INSERT INTO t VALUES (3)")
client.runSqlHive("CREATE TABLE tabNullType AS SELECT NULL AS col
FROM t")
spark.table("tabNullType").show()
spark.table("tabNullType").printSchema()
}
```
Is this what you want?
