Now on the second node (ubuntu2) start the node with ''/opt/cassandra/bin/cassandra'' , and start creating the cluster.
First create the proper tokens for a 4 node cluster, by using the following py :
%%prettify
{{{
# Number of nodes in the cluster
num_node = 4
for n in range(num_node):
print int(2**127 / num_node * n)
}}}
%%
