The comment on this change is: Removing the erroneous link.. http://wiki.apache.org/cassandra/FAQ?action=diff&rev1=109&rev2=110 -------------------------------------------------- <<Anchor(clustername_mismatch)>> == Cassandra says "ClusterName mismatch: oldClusterName != newClusterName" and refuses to start == - To prevent operator errors, Cassandra stores the name of the cluster in its system table. If you need to rename a cluster for some reason, it is safe to remove system/LocationInfo* after forcing a compaction on all ColumnFamilies (with the old cluster name) if you've specified the node's token in the config file, or if you don't care about preserving the node's token (for instance in single node clusters.) + To prevent operator errors, Cassandra stores the name of the cluster in its system table. If you need to rename a cluster for some reason, it is safe to remove system/LocationInfo* after forcing a compaction on all !ColumnFamilies (with the old cluster name) if you've specified the node's token in the config file, or if you don't care about preserving the node's token (for instance in single node clusters.) <<Anchor(batch_mutate_atomic)>>
