Gary Dusbabek commented on CASSANDRA-1191:
------------------------------------------
It worked before, and I don't think it's unreasonable to "seed" a single node
with keyspaces before bringing other nodes online. If this isn't the case,
we'll want to spell that out clearly: load your schema *after* you have enough
nodes online to support full replication.
> Make Strategy classes fail if asked to fulfil an impossible replication
> request

> I added to RSECT in CASSANDRA-1147,
> // TODO DSS is asked to provide a total of 6 replicas, but we never
> give it 6 endpoints.
> // thus we are testing undefined behavior, at best.
> This is easiest to cause in DSS but it can afflict other Strategies too.
> Let's update the ARS contract to state that calculateNaturalEndpoints (hence
> getNaturalEndpoints too) will throw IllegalStateException if more replicas
> are requested than the known endpoints (for DSS, this would apply on a per-DC
> basis) and amend the Strategy classes to check for this.
