I believe the actual issue you have is "stuck schema for this
keyspace," not anything to do with replication factor. To test this,
try adding a ColumnFamily and see if it works. I bet it won't.

There are anecdotal reports in the 1.0.8-1.1.5 timeframe of this
happening. One of the causes is the one aaron pasted, but I do not
believe that is the only cause of this edge case. As far as I know,
however, there is no JIRA ticket open for "stuck schema for keyspace"
... perhaps you might want to look for and/or open one?
