Utku: are you able to test this patch?

cassandra-cli "describe keyspace xxx" reported "Replication Factor: 1" ) :-$

It does not work for me because i'm using ByteOrderedPartitioner which doesn't
return multiple endpoints for each TokenRange returned by:
client.describe_ring(..) <-- storageService.getRangeToEndpointMap(..) <--
getRangeToAddressMap(..) <-- getRangeToAddressMap(..) <--
constructRangeToEndpointMap(..) <-- replicationStrategy.getNaturalEndpoints(..)
(Or maybe endpoints are not suppose to reference available replicas. stu?)

> using the same directives in the sample code:
> When I start the CFInputFormat to read a CF in a keyspace of RF=3 on a 4-node
> cluster:
> - If all the nodes are all up, everything works fine and I don't have any
> problems walking through the all data in the CF, however
> - If there's a node down, the hadoop job does not even start, just dies
> without any errors or exceptions.
> So I'm really sorry for not being able to post any errors or exceptions,
> though it's really easy to reproduce. Just startup a cluster and take one
> node down and you're there :)
