Subject [jira] [Commented] (CASSANDRA-5107) node fails to start because host id is missing
Date Fri, 18 Jan 2013 16:02:15 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13557306#comment-13557306
] 

Sylvain Lebresne commented on CASSANDRA-5107:
---------------------------------------------

Can't that be because we start gossiper before setting the applicationState (including the
host_id)? Granted we have a 1 second delay before really starting the gossipTask, but if those
stack traces come from the test bot, maybe sometime the machine is slow enough that you can
have a whole second interruption of the thread initializing the server.

In any case, this feel dangerous to me. Maybe we could split Gossiper.start into a Gossiper.init(),
followed by the addition of the applicationstate that we expect to be always there, and then
we start it.
