Tyler Hobbs commented on CASSANDRA-7510:
----------------------------------------

Well, this is definitely an improvement over what we currently have, so I'll +1 \
committing this for now and open a new ticket to figure out the best way to delay UP \
notifications until the rpc server has started.

> URL: https://issues.apache.org/jira/browse/CASSANDRA-7510
> Project: Cassandra
> Issue Type: Bug
> Reporter: Joost Reuzel

> 
> Currently, Cassandra will notify clients when a new node is added to a cluster. \
> However, that node is typically not usable yet. It first needs to gossip its key \
> range and finish loading all its assigned data before it allows clients to connect. \
> Depending on the amount of data this may take quite a while. The clients in the \
> mean time have no clue about the bootstrap status of that node. The only thing they \
> can do is periodically check if it will accept a connection.  My proposal would be \
> to send an additional UP event when the bootstrap is done, this allows clients to \
> mark the node initially as down/unavailable and simply wait for the UP event to \
> arrive. Kind regards,
> Joost
