Jonathan Ellis commented on CASSANDRA-195:
------------------------------------------
How does the new node (node Z) know that there are no nodes that were down at
the time Z was brought up, but which need to send it data?
(Is this addressed at all in the existing bootstrap code? I think what will
happen is that a node D that is down at the time of bootstrap will never send
the data over.)

> Key: CASSANDRA-195
> URL: https://issues.apache.org/jira/browse/CASSANDRA-195
> Project: Cassandra
> Issue Type: Improvement
> Affects Versions: trunk
> Environment: all
> Reporter: Sandeep Tata
> Fix For: trunk
>
>
> When you add a node to an existing cluster and the map gets updated, the new
> node may respond to read requests by saying it doesn't have any of the data
> until it gets the data from the node(s) the previously owned this range (the
> load-balancing code, when working properly can take care of this). While this
> behaviour is compatible with eventual consistency, it would be much
> friendlier for the new node not to "surface" in the EndPoint maps for reads
> until it has transferred the data over from the old nodes.
