Subject Hardware change of a node in the cluster
Date Mon, 04 Oct 2010 09:58:51 GMT
Hey All,

Recently I've tried to upgrade (hw upgrade) one of the nodes in my cassandra
cluster from ec2-small to ec2-large.

However, there were problems and since the IP of the new instance was
different from the previous instance. The other nodes didnot recognize it in
the ring.

So what should be the best practice for a complete hardware change of one
node in the cluster while keeping the data that it has.
