Subject [jira] [Commented] (CASSANDRA-2825) Auto bootstrapping the 4th node in a 4 node cluster doesn't work, when no token explicitly assigned in config.
Date Thu, 21 Jul 2011 13:21:59 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13068974#comment-13068974
] 

Brandon Williams commented on CASSANDRA-2825:
---------------------------------------------

Impressive, I have no idea how this is breaking testTokenRoundtrip():

{noformat}
    public void testTokenRoundtrip() throws Exception
    {  
        StorageService.instance.initServer();
        // fetch a bootstrap token from the local node
        assert BootStrapper.getBootstrapTokenFrom(FBUtilities.getLocalAddress()) != null;
    }
{noformat}

The log just shows a bunch of attempts to connect to the seed (127.0.0.2) which hasn't started
yet.

> This was done in sequence.  A, B, C, and D.  Node A with token 0 explicitly set in config.
 The rest with auto_bootstrap: true and no token explicitly assigned.  B and C work as expected.
D ends up stealing C's token.
