Subject [jira] [Commented] (CASSANDRA-1361) Introduce ability to change seed addresses on a running node
Date Mon, 17 Jul 2017 20:29:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1361?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16090498#comment-16090498
] 

Brandon Williams commented on CASSANDRA-1361:
---------------------------------------------

Since seed providers were introduced, the seed list is reloaded anytime a seed is removed.
 So to avoid a restart, first promote an existing node to a seed in the yaml files, then remove
the defunct seed with removenode and the promoted seed will become active.

> Since seed nodes are not only used for bootstrap but also for gossiping it would be really
useful to be able to replace seed addresses on running nodes without restarting them since
at the moment you can only change seed nodes by changing configuration file and then restarting
cassandra.
> My usecase is to be able to replace failed seed nodes in cassandra without having to
proceed to a rolling restart of the cluster. And also to be able to start X nodes that initially
might be independent but then would all join an existing ring by changing their seeds.
