Carl Yeksigian commented on CASSANDRA-10242:
--------------------------------------------
I replaced the {{conf/cassandra-rackdc.properties}} change with a comment for
people upgrading from {{SimpleSnitch}}, so that it's safe for people who are
already using {{GossipingPropertyFileSnitch}} to upgrade.
Yeah, that was an oversight; I've removed that change.
> Validate rack information on startup

> Reporter: Jonathan Ellis

> Fix For: 3.0.0 rc2, 2.2.3, 2.1.11

>
> 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.)
