> When an Avro schema is invalid, AvroSerDe returns an error message instead of throwing an exception. This is described in {{AvroSerdeUtils.determineSchemaOrReturnErrorSchema}}:
> {noformat}
>   /**
>    * Attempt to determine the schema via the usual means, but do not throw
>    * an exception if we fail.  Instead, signal failure via a special
>    * schema.  This is used because Hive calls init on the serde during
>    * any call, including calls to update the serde properties, meaning
>    * if the serde is in a bad state, there is no way to update that state.

> I believe we should find a way to provide a better experience to our users.
