I can confirm that not all nodes receive schema, not only new, but some old also, while old one were dead on time of keyspace creation and upon return have not received an update. Sometime even all nodes running fine, not all have received schema update. Viktor -Original Message- From:

I was unable to duplicate this problem using a 3 node cluster. Here were my steps: 1. bring up a seed node, give it a schema using loadSchemaFromYaml 2. bring up a second node. it received schema from the seed node. 3. bring the seed node down. 4. bring up a third node, but set it's seed to be the

I've been trying a number of combinations of starting/stopping machines with and without various seeds and I can't recreate the problem now. I strongly suspect it was because we were trying to use the DatacenterShardStrategy code. Between changing snitches and shard classes, we haven't been a

Fair enough. But doesn't that mean that the node that comes up has the same token? I suppose the answer is that the auto bootstrap process is smart enough to figure out which range needs help. Thanks much, Jonathan. --sriram. On Jun 11, 2010, at 8:59 PM, Jonathan Ellis wrote: repartitioni

I saw the operations page, but didn't get what I was looking for. What I meant by my earlier statement was that it is not clear to me who assigns the token to a new node; if a node goes down, and another process comes up, is (a) the token assigned to it automatically by consensus (and the b
