I got this issue solved by using nodetool -h localhost move &lt;new_token&gt;.

You will need at least 0.8.2 for the OpsCenter functionality to work. </p> http://www.datastax.com/support-forums/topic/newbie-question-change-cassandrayaml-doesnt-take-effect#post-7255 Wed, 31 Oct 2012 05:48:29 +0000 txie 7255@http://www.datastax.com/support-forums/ <p>Thanks Sven. I tried to make the "Move" action by using the opscenter, got error dialog</p> <p>Error during move: The DC for node 10.7.90.18 has not been determined. This check is used to prevent nodes from running out of disk space during a move. </p> http://www.datastax.com/support-forums/topic/newbie-question-change-cassandrayaml-doesnt-take-effect#post-7241 Wed, 31 Oct 2012 00:03:37 +0000 Sven 7241@http://www.datastax.com/support-forums/ <p>Once a server has been run once, the initial_token is no longer being used (it's only used for the initial determination of the servers token). Please check <a href="http://wiki.apache.org/cassandra/Operations#Token_selection" rel="nofollow">http://wiki.apache.org/cassandra/Operations#Token_selection</a> on how to change token assignments. The easiest way to manage your nodes is through OpsCenter Enterprise Edition <a href="http://www.datastax.com/docs/opscenter/online_help/cluster/node_actions#rebalance-cluster" rel="nofollow">http://www.datastax.com/docs/opscenter/online_help/cluster/node_actions#rebalance-cluster</a>.</p> <p>Thanks,<br /> Sven </p> http://www.datastax.com/support-forums/topic/newbie-question-change-cassandrayaml-doesnt-take-effect#post-7228 Tue, 30 Oct 2012 19:15:17 +0000 txie 7228@http://www.datastax.com/support-forums/ <p>Here is what I did<br /> 1. stop cassandra service with: service dse stop<br /> 2. open up /etc/dse/cassandra/cassandra.yaml and change the 'initial_token'<br /> 3. restart cassandra with: service dse start</p> <p>But I don't see the change takes effect, nodetool still shows the old token.
