I've tried to migrate 1.1 to 1.2 and failed with the nodes tokens. Since I have 5 nodes, then I've done initial_tokens for each like this: 0,1,2,3,4 and it worked. Each node got a number starting with zero. </p> http://www.datastax.com/support-forums/topic/cassandra-12-beta-multinode-setup#post-7735 Fri, 30 Nov 2012 16:03:17 +0000 nickmbailey 7735@http://www.datastax.com/support-forums/ <p>The DataStax Documentation for 1.2 is still being worked on at the moment.

Unfortunately there currently isn't much documentation on the 1.2 beta. You have a couple of options</p> <p>* Use RandomPartitioner. You can change this in cassandra.yaml. With this the token generating tool will work.<br /> * Use vnodes. The 1.2 release includes the concept of vnodes where instead of one range, a node owns many distinct ranges. You can set this in cassandra.yaml as well and there are instructions in that file.<br /> * If you want to use the Murmur3Partitioner without vnodes you can run this python command to get appropriate tokens. Replacing "X" with the number of nodes you have:</p> <p>python -c 'print [((2**64 / X) * i) - 2**63 for i in range(X)]' </p> http://www.datastax.com/support-forums/topic/cassandra-12-beta-multinode-setup#post-7687 Wed, 28 Nov 2012 09:07:24 +0000 sridanu 7687@http://www.datastax.com/support-forums/ <p>Tx nick for your reply. </p> <p>I just used the token gen tool within the Cassandra release. Could you kindly point me to where you got this info from. </p> http://www.datastax.com/support-forums/topic/cassandra-12-beta-multinode-setup#post-7658 Fri, 23 Nov 2012 18:10:18 +0000 nickmbailey 7658@http://www.datastax.com/support-forums/ <p>Cassandra 1.2 uses a new partitioner called 'Murmur3Partitioner'. The murmur 3 partitioner uses tokens in the range -2^63 to 2^63 - 1. It looks like the token you are specifying is outside of that range. </p> http://www.datastax.com/support-forums/topic/cassandra-12-beta-multinode-setup#post-7646 Thu, 22 Nov 2012 17:06:56 +0000 sridanu 7646@http://www.datastax.com/support-forums/ <p>Hi,</p> <p>im testing the beta on a 2 node setup.
