We're exploring a data processing procedure where we snapshot our production cluster data and move that data to a new cluster for analysis but I'm having some strange issues where the analysis cluster is still somehow aware of the production cluster (i.e. the production cluster ring is trying to include nodes from the other cluster with the same token).
The seed addresses in cassandra.yaml definitely prohibit this type of intersection between the two clusters so I'm guessing that it has something to do with the information in the system sstables.
Is there anyway to duplicate raw sstables in an effort to "copy" a cluster such that the copied cluster has a different name? I know this usually results in a "saved cluster name X != Y" sort of error but it looks like we need to find some sort of way to do this logical separation.
Any help would be much appreciated!
