Jeremy Hanna commented on CASSANDRA-12816:
------------------------------------------
When [~jjordan] says "it will work", it won't fail. It will work like it did
before. That is, in the scenario where you set auto bootstrap to false when
you add the new datacenter nodes - since SimpleStrategy ignores datacenter
information, some of the new nodes will take ownership for some of the ranges
for the SimpleStrategy keyspace data. So a rebuild from the source datacenter
won't get the data that the new datacenter nodes own. So you won't have all of
the data from the SimpleStrategy keyspaces when everything is done. You can
make sure you don't replicate to the new datacenter in your NTS keyspace config
and do auto bootstrap = true and actually get the data when the new nodes take
ownership of those ranges. However, then you're still left with having to
migrate SimpleStrategy keyspaces to NetworkTopologyStrategy with two
datacenters anyway because you really don't want SimpleStrategy with more than
one datacenter.
This is why you always, *always* change to NetworkTopologyStrategy on all
non-LocalStrategy keyspaces before adding a second datacenter.

> Project: Cassandra
> Issue Type: Bug
> Reporter: Jai Bheemsen Rao Dhanwada
> Priority: Critical
>
> 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?
