You should check the cassandra.yaml file.  There is an initial_token in that file that you
should have set.  The comment above that property reads

# You should always specify InitialToken when setting up a production
# cluster for the first time, and often when adding capacity later.
# The principle is that each node should be given an equal slice of
# the token ring; see
# for more details.
# If blank, Cassandra will request a token bisecting the range of
# the heaviest-loaded existing node.  If there is no load information
# available, such as is the case with a new cluster, it will pick
# a random token, which will lead to hot spots.

Naturally, he is referring to that link when he says manual ;) AND notice the "which will
lead to hot spots" comment.

Did you set up the tokens the way
the manual says?
