Hi Prem,
I think system_auth keyspace uses SimpleStrategy by default and thus not
applicable across dc.Please alter the keyspace to use NetworkTopology and set
appropriate replication factor for both Dc. After that you can run full repair
across dc on this keyspace.
I dnt see any drawbacks o
Hi,
We have an existing cluster consisting of 3 DCs. Authentication is enabled.
I am trying to add a new DC. I followed the steps mentioned at:
http://docs.datastax.com/en/cassandra/2.0/cassandra/operations/ops_add_dc_to_cluster_t.html
Bit, I still can't login to any of the nodes in the new DC us

That article is about creating a new cluster, to add an a DC to an ex

I see no reason to restart all nodes. You can continue to use seed from
first DC - seed used for loading ring configuration(locations, token
ranges, etc), not data.

If I understand you correctly, GossipingPropertyFileSnitch is useful for
manipulations with nodes within a single DC, but to add a new DC without
having to restart every node in all DCs (because seeds are specified in

You should configure the seeds as recommended regardless of the snitch used.
You need to update the yaml file to start using the GossipingPropertyFileSnitch
but after that it reads the cassandra-rackdc.properties file to get information
about the node. It reads uses the information in gossip to
As far as I understand, GossipingPropertyFileSnitch supposed to provide
more flexibility in nodes addition/removal. But what about addition of a
