Chris Herron commented on CASSANDRA-3975:
-----------------------------------------

Suggest that for 1.0.x, UnserializableColumnFamilyException might be better 
named UnknownColumnFamilyException (since unknown cfId is the only time its 
ever thrown. It could then be caught within HHOM.deliverHintsToEndpointInternal 
and the affected hint deleted. Its unclear to me if this needs to be tackled 
differently for 1.1.
                
> Hints Should Be Dropped When Missing CFid Implies Deleted ColumnFamily

> If hints have accumulated for a CF that has been deleted, Hinted Handoff 
> repeatedly fails until manual intervention removes those hints. For 1.0.7, 
> UnserializableColumnFamilyException is thrown only when a CFid is unknown on 
> the sending node. As discussed on #cassandra-dev, if the schema is in 
> agreement, the affected hint(s) should be deleted to avoid indefinite repeat 
> failures.
