Gary Dusbabek commented on CASSANDRA-1191:
------------------------------------------
This breaks SS.calculatePendingRanges on a new cluster (1 node) where a
keyspace with RF>1 has been created (e.g.: via schematool) and a second node is
trying to bootstrap.
We should find a better place to throw this error, probably in the ARS methods
that call it. Fallout can be tracked in CASSANDRA-1343.

> 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.
