to me it makes sense that if hinted handoff is off then cassandra cannot satisfy 2 out of every 3rd writes writes when one of the nodes is down since this node is the designated node of 2/3 writes. But I don't remember reading this somewhere. Does hinted handoff affect David's situation? (David, did you disable HH in your storage-config? <HintedHandoffEnabled>false</HintedHandoffEnabled>)
