----------------------------------------
Resolving as 'not a problem', since the problem was an error in your dc name.

> i have replicated the issue on my personal cluster using VMs.
> we have many keyspaces and users developing on the Dev Cluster we are trying
> to stretch.
> With my current VMs (10 total) i can create a 2 DC cluster dc1 and dc2.
> i rebuild all nodes - clear data dirs and restart dc1.
> i also clear data dirs on dc2 nodes, i donot restart yet,
> now i have single dc1 5 nodes cluster.
> snitch - GossipingPropertyFileSnitch
> i create keyspaces on DC1
> after i alter keyspaces with replication dc1 3 dc2 0 i can no longer
> query tables - not enough replicas available for query at consistency ONE.
> same error with CQL using consistency local_one
> continue with procedure, startup dc2 nodes,
> alter replication on keyspaces to dc1 3 dc2 2
> from dc2 nodes , nodetool rebuild -- dc1 fails
> i am attaching detailed steps with errors and cassandra.yaml
