Jonathan Ellis commented on CASSANDRA-3219:
-------------------------------------------
bq. I think that it's more complicated to explain/understand how to choose
between those two options
Huh? This is a HUGE simplification because initial_token behavior depends only
on initial_token. The old behavior (where initial_token=empty behavior does
one thing with auto_bootstrap=true, and another with a_b=false) was ENORMOUSLY
confusing: EVERY training class I taught was baffled by this.
Further, the old behavior doesn't let you specify bootstrap/random or
nobootstrap/auto, both of which are valid things to do.
bq. based on whether there is a keyspace defined already
I don't see how this helps the situation Jake describes.
bq. just force user to set a token
This is a non-starter.
> Nodes started at the same time end up with the same token

> Since autoboostrap is defaulted to on when you start a cluster at once
> (http://screenr.com/5G6) you can end up with nodes being assigned the same
> token.
