Andy Cobley commented on CASSANDRA-5768:
----------------------------------------
I tried 5768.txt on cassandra-trunk. It does halt cassandra if the seed can't
be connected (with java.lang.IllegalStateException: Unable to contact any
seeds!)
However it also halts with the same exception if seeds is set to 127.0.0.1 (the
default in cassandra.yaml):
seed_provider:
# Addresses of hosts that are deemed contact points.
# Cassandra nodes use this list of hosts to find each other and learn
# the topology of the ring. You must change this if you are running
# multiple nodes!
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
# seeds is actually a comma-delimited list of addresses.
# Ex: "<ip1>,<ip2>,<ip3>"
- seeds: "127.0.0.1"
So thats not correct I guess.

> Setting up a new test cluster using 2.0.0-beta1 and I noticed the following
> behaviour with vnodes turned on.
> I bring up one node all well and good. however if I bring up a second node,
> that can't contact the first (the first being the seed for the second) after
> a short period of time, the second goes ahead and assumes it's the only node
> and bootstraps with all tokens.
> NOTE also this email from Robert Coli
> To: [email protected]
> Obviously if you have defined a seed and cannot contact it, the node should
> not start as a cluster of one. I have a to-do list item to file a JIRA on the
> subject, but if you wanted to file and link us, that'd be super. :)
> Startup trace (from the can't contact the seed messages below).
