Jonathan Ellis commented on CASSANDRA-4427:
-------------------------------------------
bq. I believe this simpler fix doesn't handle the case of boostrapping multiple
nodes into an existing cluster.
We've never tried to prevent this, except by saying "thou shalt space
bootstraps apart two minutes," because the only way to stop it is to drop the
"balanced" token picking altogether. Adding "bootstrap in progress" concept
does nothing for this one way or the other.
bq. Namely, in that case, that will have a schema and so the node will have a
system table by the time it checks for it and we'll end up picking the same
token for multiple nodes.
This is exactly how it's supposed to work: if there's a schema, we use
"existing cluster mode" and pick a token to divide the range of the heaviest
node (and cross our fingers that the user is spacing things out enough between
node additions). If there's no schema, we use "new cluster mode" and pick a
random token.
Let the record show that back in CASSANDRA-3219 I said this was confusing
behavior and we should add explicit initial_token modes instead of trying to
make it magical. :)
