CCM configure rack per node

[lehnerj]

I would like to setup a multi data center (DC) scenario with multiple racks per DC. Is this possible with ccm?

Default config of snitch is SimpleSnitch.

SimpleSnitch: This is the default snitch, but it is good only for
development environments. This snitch is unaware of datacenters or
racks and thus is unusable for multi-datacenter environments

You have to change to GossipingPropertyFileSnitch then change config in file

${node_name}/conf/cassandra-rackdc.properties

Default value is

dc=dc1
rack=rack1

I try to do the same as @lehnerj. I first stop the cluster and after that I adjust the snitch type and the rackdc properties file. However, after starting the cluster again, the old rack name is still displayed on all three nodes when I run nodetool status. Is there something that I'm missing? Maybe flush a cache or something like that?

@markvdlaan93: CCM is working for me with multi-dc setup.
