Review Comment:
Can you try
```
val isSchemaReAdd = scan.readSchema().fieldNames.exists(n => table match {
case t: SparkTable => t.table() match {
case t: BaseTable =>
val oldSchemas = t.schemas()
oldSchemas.remove(t.schema().schemaId())
val currentId = t.schema().findField(n).fieldId()
oldSchemas.values().stream().anyMatch{v => {
val oldField = v.findField(n)
oldField != null && oldField.fieldId() != currentId
}
}
}
})
if (isSchemaReAdd) {
return ValidationResult.failed("Contains re-added schema")
}
```
