Jonathan Ellis commented on CASSANDRA-564:
------------------------------------------

I don't see where we do data transfers to move the right data to the node whose 
range expands by the dead node being removed, or updating other replicas now 
responsible for copies.  We might need a new gossip state for that.

If that is done should we remove decommission as a redundant special case?

> Provide recoverability when a node dies and it is impossible to get the same 
> IP.

> From the descriptions on the mailing list, when a node dies permanently from 
> hardware or other failure and you need to replace it, it must have the same 
> IP.  For people running in cloud environments, this is often times 
> impossible.  So it would be very useful if there was a way to replace a node 
> with a new node without requiring the same IP.
