Review comment:
Hi, @HeartSaVioR . The original code looks like the same with
`branch-2.4` but the issue is reported at 3.0.0+. Could you confirm that this
is 3.0.0-only issue or not?
```scala
override lazy val resolved: Boolean = {
table.resolved && query.resolved && query.output.size ==
table.output.size &&
query.output.zip(table.output).forall {
case (inAttr, outAttr) =>
// names and types must match, nullability must be compatible
inAttr.name == outAttr.name &&
DataType.equalsIgnoreCompatibleNullability(outAttr.dataType,
inAttr.dataType) &&
(outAttr.nullable || !inAttr.nullable)
}
}
```
