Jonathan Ellis commented on CASSANDRA-840:
------------------------------------------
I was looking at this fragment
+ // reinitialize the table.
+ Table.open(ksm.name).addCf(cfm.cfName);
+ DatabaseDescriptor.setTableDefinition(ksm, newVersion);
+
+ // force creation of a new commit log segment.
+ CommitLog.instance().forceNewSegment();
isn't that saying the CLS happens afterwards, not before? (which only makes
sense, since how can it know about the new entry until it's in the table / DD)
> Add the ability to add/remove/rename column families on a single node.
