Jonathan Ellis resolved CASSANDRA-12.
-------------------------------------
Resolution: Invalid
Assignee: (was: Chris Goffinet)
isAlive(endpoint, epState, false);
is what sets epState.isAlive to false.
> Gossiper should set the Node is dead when notifies the subscriber

> When the gossiper is notified by Failure Detector that one node is dead, it
> would tell the storage service by the onChange() cacallback. However, the
> gossiper doesn't set the EndPointState to be dead. Please check following
> code snippet from Gossiper.java
> public void suspect(EndPoint endpoint)
> {
> EndPointState epState = endPointStateMap_.get(endpoint);
> if ( epState.isAlive() )
> {
> logger_.info("EndPoint " + endpoint + " is now dead.");
> isAlive(endpoint, epState, false);
> /* Notify an endpoint is dead to interested parties. */
> EndPointState deltaState = new
> EndPointState(epState.getHeartBeatState());
> /* add deltaState.isAlive(false); here */
> doNotifications(endpoint, deltaState);
> }
> And the storage service would detect it as the node comes back after network
> partition and start a hinted transmit. Please see the code snippet in
> StorageService.java
> else --> if( nodeIdState == null)
> {
> /*
> * If we are here and if this node is UP and already has an entry
> * in the token map. It means that the node was behind a network
> partition.
> */
> if ( epState.isAlive() &&
> tokenMetadata_.isKnownEndPoint(endpoint) )
> {
> logger_.debug("EndPoint " + ep + " just recovered from a
> partition. Sending hinted data.");
> doBootstrap(ep, BootstrapMode.HINT);
> }
> }
