Invalid value(s) for DATACENTERS

Error message

Invalid value(s) for DATACENTERS '%s',All values must be valid datacenters

What it means

InvalidRequestException from DCPermissions.validate: the set of datacenter names supplied for a role's DATACENTERS option contains one or more names that are not valid datacenters in the current cluster metadata (Datacenters.getValidDatacenters). The difference set names exactly which values are unknown.

Solutions

1. Verify datacenter names with nodetool status or cluster metadata and correct typos
2. Create/enable the intended datacenter before referencing it
3. Remove decommissioned or renamed datacenters from the role's DATACENTERS option
