-----------------------------------------------------

             Summary: Rebuild failing while adding new datacenter
                 Key: CASSANDRA-12816
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12816
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jai Bheemsen Rao Dhanwada


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?
