> This is a follow up to CASSANDRA-18543
> Although that ticket added ability to set cassandra.gossip_settle_min_wait_ms 
> this is tedious and error prone. On a node just observed a 79 second gap 
> between waiting for gossip and the first echo response to indicate a node is 
> UP.
> The problem being that do not want to start Native Transport until gossip 
> settles otherwise queries can fail consistency such as LOCAL_QUORUM as it 
> thinks the replicas are still in DOWN state.
> Instead of having to set gossip_settle_min_wait_ms I am proposing that 
> (outside single node cluster) wait for UP message from another node before 
> considering gossip as settled. Eg.
> {code:java}
>             if (currentSize == epSize && currentLive == liveSize && liveSize 
> > 1)
>             {
>                 logger.debug("Gossip looks settled.");
>                 numOkay++;
>             } {code}
