Review Comment:
   I agree that using a `Precondition.check` here seems more appropriate but I 
just wanted to mention that the original code threw a `NoSuchTableException` 
when the identifier was invalid as can be seen in 
https://github.com/apache/iceberg/blame/79c88a1775c4e2019fff00de7520826388158424/hive-metastore/src/main/java/org/apache/iceberg/hive/HiveCatalog.java#L225-L227
   so we might need to be careful here in changing the exception being thrown 
as I'm not sure whether that would have any implications
