------------------------------------------

             Summary: Add an Ack/Retry for merkle tree sending
                 Key: CASSANDRA-5393
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5393
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jeremiah Jordan


Can we add an Ack/Retry around passing merle tree's around in repair?  If the following fails,
the repair hangs for ever on the coordinating node.

            Message message = TreeResponseVerbHandler.makeVerb(local, validator);
            if (!validator.request.endpoint.equals(FBUtilities.getBroadcastAddress()))
                logger.info(String.format("[repair #%s] Sending completed merkle tree to %s
for %s", validator.request.sessionid, validator.request.endpoint, validator.request.cf));
            ms.sendOneWay(message, validator.request.endpoint);
