    IIUC, here I think we should test when the schema read by `getRawTable` (i.e., `rawTable`)
is different than the schema stored in table properties. 
    Previously because two copies of schema are different, you will get the `NoSuchElement`
too. That's why we should call `restoreTableMetadata` here for hive serde tables.
