Jonathan Ellis resolved CASSANDRA-2705.
---------------------------------------

       Resolution: Not A Problem
    Fix Version/s:     (was: 0.7.7)
                       (was: 0.8.1)

schema-sample isn't really the place to explain replication and consistency levels.

> After stumbling upon this pitfall *twice* (yeah, it's okay to call me stupid, but I'm your customer anyways :) I suggest a simple comment in the Keyspace1 example like this:
> replication_factor defines the total number of nodes holding the data.
> quorum with a RF < 3 provides no fault tolerance, because with a RF=2
> data is written to 2 nodes in total (if one fails, only one remaining
> can be checked while 2 are actually required to meet quorum).
