Hi all, I have the similar question.
After killing one of the node of the cluster, I find that only the node's status changed: from "Up" to "Down". But all the data of the node left unchanged according to the "Load" field of the nodeprobe's output info. According to the Dynamo paper, when a node failed, its neighbors should change their data topology and ensure the number of replicas. How does Cassandra ensure that? 2009/12/16 <[email protected]> > Hello guys: > I have some stupid question to ask... > > 1.
