> Hello All,
> I have single datacenter with 3 C* nodes and we are trying to expand the cluster to another region/DC. I am seeing the below error while doing a "nodetool rebuild -- name_of_existing_data_center" .  
> {code:java}
> [user@machine ~]$ nodetool rebuild DC1
> nodetool: Unable to find sufficient sources for streaming range (-402178150752044282,-396707578307430827] in keyspace system_distributed
> See 'nodetool help' or 'nodetool help <command>'.
> [user@machine ~]$
> {code}
> {code:java}
> user@cqlsh> SELECT * from system_schema.keyspaces where keyspace_name='system_distributed';
>  keyspace_name | durable_writes | replication
> ---------------+----------------+-------------------------------------------------------------------------------------
>  system_distributed |           True | {'class': 'org.apache.cassandra.locator.SimpleStrategy', 'replication_factor': '3'}
> (1 rows)
> {code}
> To overcome this I have updated system_distributed keyspace to DC1:3 and DC2:3 with NetworkTopologyStrategy
> C* Version - 3.0.8
> Is this a bug that is introduced in 3.0.8 version of cassandra? as I haven't seen this issue with the older versions?
