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.

> Validate rack information on startup

> 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.)
