Should this really be possible? In the documentation at > http://docs.datastax.com/en/cassandra/2.1/cassandra/initialize/initializeMultipleDS.html > it's stated that you should ??Choose the name carefully; renaming a data > center is not possible??, but with this functionality it doesn't seem > impossible(maybe a bit hard with changing replication etc.). > This functionality was introduced by CASSANDRA-5897 so I'm guessing there is > some use case for this? > Personally I would want the DC/rack settings to be as restricted as the > cluster name, otherwise if a node could just join another data center without > removing it's local information couldn't it mess up the token ranges? And > suddenly the old data center/rack would loose 1 replica of all the data that > the node contains. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
