Hi,

I'm using cassandra = 1.2.3.

I've successfully clustered 3 machines and created a = keyspace with replication factor 3.

Node1 seeds Node2
Node2 = seeds Node1
Node3 seeds Node1

I insert an entry using = node1.

Using cqlsh from another node, I try to delete the item by = sending out the delete command.

After sending the command, there = seems to be no error but when I try to select the item it is still = there.

When I try to send the same delete command from node1 = cqlsh it seems to work.

Basically any delete command i send from = the other nodes doesn't work unless i use it using node1. However I can = select the items using the other nodes.

Is this a problem? I = can't seem to modify objects from node1 using other nodes. Truncate = works though.

Please = help

Thanks!
Byron
