Subject Re: If one seed node crash, how can I add one seed node?
Date Tue, 07 Dec 2010 15:01:20 GMT
Yes, cassandra only reads the configuration when it starts up. However seed
nodes are only used when a node starts. After that they aren't needed. There
should be no reason to restart your cluster after adding a seed node to
 your cluster.
