Subject Re: SOLVED: Problem upgrading to 0.8.3 - "replication_factor is an option for SimpleStrategy, not NetworkTopologyStrategy"
Date Wed, 10 Aug 2011 14:59:02 GMT
Martin,

Thanks for the report!  (Did I miss an earlier email about this?
Because SOLVED is the first I saw.)

I've created https://issues.apache.org/jira/browse/CASSANDRA-3011 and
attached a patch to fix the problem.
