Jonathan Ellis resolved CASSANDRA-5310.
---------------------------------------
Resolution: Not A Problem
The {{system_auth}} keyspace only has a single replica by default, since that's
all we can rely on being present everywhere. You are welcome to configure it
to replicate using NTS and as many replicas as you see fit.
