Andy Cobley commented on CASSANDRA-5768:
----------------------------------------
Jason,
You code for build list should read:
{code}
private void buildSeedsList()
{
Set<InetAddress> seeds = DatabaseDescriptor.getSeeds();
for (InetAddress seed : seeds)
{
if (seed.equals(FBUtilities.getBroadcastAddress()) &&
seeds.size() == 1)
seedContacted = true;
else
seeds.add(seed);
}
}
{code}
Sadly that throws an exception at startup:

> If a Seed can't be contacted, a new node comes up as a cluster of 1
> -------------------------------------------------------------------
>
> Key: CASSANDRA-5768
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5768
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 2.0 beta 1
> Reporter: Andy Cobley
> Assignee: Brandon Williams
> Priority: Minor
> Fix For: 2.0 beta 2
>
> Attachments: 5768.txt
>
>
> 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: u...@cassandra.apache.org
> 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).
