Nicolas Lalevée commented on CASSANDRA-3490: -------------------------------------------- I am effectively hit by some concurrency issue, I had this issue with 0.8. I didn't know that this error message was about schema disagreement. Thanks for the quick reply. > Error while creating many column families: "ConfigurationException: Previous > version mismatch. cannot apply." > ------------------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-3490 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3490 > Project: Cassandra > Issue Type: Bug > Affects Versions: 1.0.2 > Reporter: Nicolas Lalevée > > Maybe a duplicate/reopen of CASSANDRA-1384 > I have a cluster of 4 cassandra nodes 1.0.2.
