Subject [jira] [Commented] (CASSANDRA-10242) Validate rack information on startup
Date Wed, 07 Oct 2015 16:45:26 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14947181#comment-14947181

Carl Yeksigian commented on CASSANDRA-10242:
--------------------------------------------

Pushed a new [dtest|https://github.com/carlyeks/cassandra-dtest/tree/10242].

I changed the default in {{conf/cassandra-rackdc.properties}} to make the move from the SimpleSnitch
to the GossipingPropertyFileSnitch easier -- these are the dc and rack which the node has
if it was started on SimpleSnitch, so it won't throw the exception in that case.

> Moving to a new rack means that different data should be stored on a node.  We already
persist rack information in a system table; we should fail startup if this doesn't match what
the snitch thinks it should be.  (Either the snitch is wrong, and needs to be fixed, or the
machine has been moved and needs to be rebootstrapped.)
