When I run</p> <p>nodetool -h localhost ring</p> <p>command on seed node, I see each nodes in up status, normal state and own 50.00% which I expect to see 25.00%. Is this normal to see the each node owns the 50.00%?</p> <p>Here is the configuration of each node;</p> <p>1. Node<br /> rpc_address: 0.0.0.0<br /> initial_token: -9223372036854775808<br /> listen_address: [IP Addres of the machine]<br /> seeds: "[IP Addres of the seed machine (1. Node)]"</p> <p>2. Node<br /> rpc_address: 0.0.0.0<br /> initial_token: -4611686018427387904<br /> listen_address: [IP Addres of the machine]<br /> seeds: "[IP Addres of the seed machine (1. Node)]"</p> <p>3. Node<br /> rpc_address: 0.0.0.0<br /> initial_token: 0<br /> listen_address: [IP Addres of the machine]<br /> seeds: "[IP Addres of the seed machine (1. Node)]"</p> <p>4. Node<br /> rpc_address: 0.0.0.0<br /> initial_token: 4611686018427387904<br /> listen_address: [IP Addres of the machine]<br /> seeds: "[IP Addres of the seed machine (1. Node)]"</p> <p>Initial Tokens calculated by using this formula; (2^64 / 4) * [NodeIndex] - 2^63</p> <p>Cassandra 1.2.1 installed in each node. Any idea about the 50.00% value for each node? </p>
