Subject [jira] [Updated] (CASSANDRA-4120) Gossip identifies hosts by UUID
Date Thu, 26 Apr 2012 20:28:51 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-4120?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eric Evans updated CASSANDRA-4120:
----------------------------------

    Description: 
Since there is no longer a one-to-one mapping of host to token, a UUID should be used to identify
a host. This impacts:

* Gossip
* Hinted Hand-off
* some JMX operations (eg. assassinateEndpointUnsafe)

_Edit: Identify host by UUID, not IP_
_Edit: Added table of patch links._
