Matthew F. Dennis commented on CASSANDRA-3705:
----------------------------------------------
I'm in favor of always requiring a that the RF for at least one DC be set when
creating a keyspace.
We should not allow a RF to be set for a DC that doesn't exist, or at the very
least not default it to a DC that doesn't actually exist.

> Key: CASSANDRA-3705
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3705
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.0.5
> Reporter: Joaquin Casares
>
> When using the AMI, which is currently set to use the EC2 snitch and the
> NetworkTopologyStrategy is set to default by the cli, all keyspaces default
> to datacenter1 being the datacenter name.
> So when running:
> {noformat}
> create keyspace test;
> {noformat}
> we get this created:
> {noformat}
> Keyspace: test:
> Replication Strategy: org.apache.cassandra.locator.NetworkTopologyStrategy
> Durable Writes: true
> Options: [datacenter1:1]
> {noformat}
> This should error out immediately rather than letting the user go on to
> discover the error later:
> {noformat}
> [default@test] set User['jsmith']['first'] = 'John';
> null
