Subject [jira] [Commented] (CASSANDRA-10242) Validate rack information on startup
Date Wed, 21 Oct 2015 01:50:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14966103#comment-14966103
] 

Jeremiah Jordan commented on CASSANDRA-10242:
---------------------------------------------

The yaml/properties/news entries about this should probably say "decommissioned" not "wiped".
 Someone is going to read that wrong and lose data.

> 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.)
