I repeat the test after verifying that the keyspace has been dropped. Also, I do not want any replication as of now that’s why replication factor is 1. But I don’t think that should be the reason for the command not propagating to other nodes.
One more thing that I observed right now is that if I create the keyspace from node 1 and node 2, it doesn’t get created but if I try to create it from node 3, it does get created. Node1 and Node 2 are Vms hosted on the same physical hardware, not sure if that has anything to do.

Let me go in a bit more detail as to what I am seeing – When I create a keyspace for the first time in a 3 node cluster, it works fine but if I drop the keyspace and try to recreate it, I see that the node received the request to create it but it didn’t delegate the request to other nodes because of which the keyspace didn’t get created on other two nodes. But the request for creating a table does get propagated to other nodes and since they can’t find that keyspace they throw an exception. I have 2 nodes as seeds, so the seeds property in cassandra.yaml for all 3 nodes looks like – seeds: "<node1ip>,<node3ip>" Following is that I see in system.log file when I enable DEBUG mode: DEBUG [SharedPool-Worker-3] 2015-01-30 16:39:37,363 Message.java:437 -

If the issue still occurs consistently, it would be interesting to turn up logging on the client side and see if something is causing the client to disconnect during the metadata refresh following the schema change. If this yields further information, please raise the issue on the driver's user mailing list.
