The DS docs go with should regarding setting the initial token to zero.
It's not a must, but you get enough convenience out of never having to
move tokens on that node that I'm not sure why you wouldn't do it.
If anyone has a compelling reason not to do so, I'm happy to hear it :)

A script that I have says the following:
$ python ctokens.py
How many nodes are in your cluster? 2
node 0: 0
node 1: 85070591730234615865843651857942052864
The first token should be zero, for the reasons discussed here:
Peter, I want to join everyone else thanking you for helping out so much
with this thread, and especially for pointing out the problems with the DS
docs on this topic. We have some corrections posted today, and will keep
looking to improve the information.

There are both Python and Java stress testing tools. I found the Java
version easier to use. These directions (which echo the README for
stress.java) may help get you going:

The DataStax packaged

standard practices for Linux-ish installation, so they might be a
good model to follow. For instance, the RHEL/CentOS package installs the

Apologies A. J. -- the reference to rack.properties is an error in the

I had a recent conversation with a Cassandra expert who had me convinced

Autobootstrap should be true, but with the important caveat that
intial_token values should be specified. Have a look at those docs, and
please give feedback on how helpful they are/aren't.

The DataStax documentation offers some answers
It sounds like one of your existing nodes already has the initial token
zero. Did you set the intial token of the first node you brought online to
zero?

A Java program should work fine. The Wiki and the DataStax documentation
use a python program for the same purpose:

I'm not sure I can say exactly why, but I'm sure those numbers can't be
correct. One node should be zero and the other values should be very long
numbers like 85070591730234615865843651857942052863.
We need another Java expert's opinion here, but it looks like your snippet

For now, I have committed a change in the misleading documentation,
substituting SimpleStrategy for NTS.
Sorry you ran into trouble due to that, mcasandra.

I don't see that you did anything

to hot spots in the ring.
