> I'm looking for a good solutions to replace dead Kubernetes worker node 
> that was running Cassandra in Kubernetes.
> Scenario:
> Cassandra cluster built from 3 pods
> Failure occurs on one of the Kubernetes worker nodes
> Replacement node is joining the cluster
> New pod from StatefulSet is scheduled on new node
> As pod IP address has changed, new pod is visible as new Cassandra node (4 
> nodes in cluster in total) and is unable to bootstrap until dead one is 
> removed.
> It's very difficult to follow the official procedure (
> https://docs.datastax.com/en/cassandra/3.0/cassandra/operations/opsReplaceNode.html),
> as Cassandra is ran as StatefulSet.
> One completely hacky workaround I've found is to use ConfigMap to supply 
> JAVA_OPTS. As changing ConfigMap doesn't recreate pods (yet), you can 
> manipulate running pods in such way that you will be able to follow the 
> procedure.
> However, that's as I mentioned, super hacky. I'm wondering if anyone is 
> running Cassandra on top of Kubernetes and has a better idea how to deal 
> with such failure?
