I had problems with write_survey. I opened a bug : https://issues.apache.org/jira/browse/CASSANDRA-9934
De : horschi [mailto:hors...@gmail.com] Envoyé : mardi 4 août 2015 15:20 À : user@cassandra.apache.org Objet : Re: auto_bootstrap=false broken? Hi Paulo, thanks for your feedback, but I think this is not what I am looking for. Starting with join_ring does not take any tokens in the ring. And the "nodetool join" afterwards will again do token-selection and data loading in one step. I would like to separate these steps: 1. assign tokens 2. have the node in a joining state, so that I can copy in data 3. mark the node as ready I just saw that perhaps write_survey could be misused for that. Did anyone ever use write_survey for such a partial bootstrapping? Do I have to worry about data-loss when using multiple write_survey nodes in one cluster? kind regards, Christian On Tue, Aug 4, 2015 at 2:24 PM, Paulo Motta <pauloricard...@gmail.com<mailto:pauloricard...@gmail.com>> wrote: Hello Christian, You may use the start-up parameter -Dcassandra.join_ring=false if you don't want the node to join the ring on startup. More about this parameter here: http://docs.datastax.com/en/cassandra/2.0/cassandra/tools/toolsCUtility_t.html You can later join the ring via nodetool join command: http://docs.datastax.com/en/cassandra/2.0/cassandra/tools/toolsJoin.html auto_bootstrap=false is typically used to bootstrap new datacenters or clusters, or nodes with data already on it before starting the process.

What currently happens: New node starts with auto_bootstrap=false and it starts serving reads immediately without having any data. Would the following be more correct: - New node should stay in a joining state - Operator loads data (e.g. using nodetool rebuild or putting in backupped files or whatever) - Operator has to manually switch from joining into normal state using nodetool (only then it will start serving reads) Wouldn't this behaviour more consistent? kind regards, Christian _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
