Merge Cassandra RACs?
Environment: Cassandra: 2.2.9, JRE: 1.8.0_74, CentOS 6/7
We have two DCs. In DC1 we have 3 RACs and in DC2 we have 6.
Because we're in a physical environment (not virtual or cloud based), we've run
short on unique rack space in DC2 and need to fix the layout problems.
Is it possible to somehow merge Cassandra racks without having to decommission
the nodes and re-add them to the cluster one by one? Or is that the correct way to accomplish this?
