As a followup, this is actually incorrect.

If you :

1) have dead (or live) node A with token X
2) start node B with token X and auto_bootstrap=false
3) node B will take over responsibility for token X from node A
without bootstrapping, due to having a higher generation number

This is a pretty good reason to make sure that you don't :

a) have auto_bootstrap=false in your config file
b) have cassandra set to auto start
