             Summary: Node enables vnodes when bounced
                 Key: CASSANDRA-7411
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7411
             Project: Cassandra
          Issue Type: Bug
         Environment: OSX 9
            Reporter: Philip Thompson
         Attachments: system.log

According to cassandra.yaml, in the information for the num_tokens setting, "Specifying initial_token will override this setting." So if exactly one initial token is set, then vnodes are disabled, regardless of if or what num_tokens are set to. This behavior is inconsistent when a node is started, versus if it has been bounced.

>From a fresh checkout of C*, if I build, then edit cassandra.yaml so that:

num_tokens: 256
initial_token: -9223372036854775808

then run bin/cassandra, C* will start correctly. I can run bin/nodetool ring and see that the node has exactly one token and it is what I set in initial_token. If I gracefully shutdown C*, then restart the node, running bin/nodetool ring shows that the node now has vnodes enabled and has 256 tokens.

I have been able to reproduce this locally on OSX using 2.0.8, 2.1 rc1, and trunk. I have not yet tested in Linux or Windows to see if it occurs there.
