Hi there, I am running a cassandra cluster (v3.0.9) with 2 DCs (4/3 nodes respectively) using endpoint_snitch: PropertyFileSnitch and I would like to decommission one node in DC1 but I wonder about what kind of actions I need to take related with the the topology settings. My cassandra-topology.properties has the those simple settings below:
x.x.x.x=DC1:RAC1 x.x.x.x=DC1:RAC1 x.x.x.x=DC1:RAC1 x.x.x.x=DC1:RAC1 x.x.x.x=DC2:RAC1 x.x.x.x=DC2:RAC1 x.x.x.x=DC2:RAC1 default=DC1:r1 My action plan is to: 1)Decomission a node in DC1 2) After node leaves cluster, edit cassandra-topology.properties in every node in the cluster 3) Question: No I need to restart all nodes in cluster? (one each time of course) Bonus question: Do I need to change the cassandra-topology.properties before move/remove nodes? Cheers, Robert, Sent with [ProtonMail](https://protonmail.com) Secure Email.
