Brandon Williams updated CASSANDRA-8336:
----------------------------------------
    Attachment: 8336-v4.txt

After wrestling with exceptions for a bit, I came up with a simpler solution.  Gossiper's stop() can examine the local state itself, and skip shutdown announcement if it doesn't exist.  We still need stopSilently (which I renamed in this patch from stopForLeaving) for cases like decom, where we aren't coming back and don't wait to mutate our state on shutdown.

> In CASSANDRA-3936 we added a gossip shutdown announcement.  The problem here is that this isn't sufficient; you can still get TOEs and have to wait on the FD to figure things out.  This happens due to gossip propagation time and variance; if node X shuts down and sends the message to Y, but Z has a greater gossip version than Y for X and has not yet received the message, it can initiate gossip with Y and thus mark X alive again.  I propose quarantining to solve this, however I feel it should be a -D parameter you have to specify, so as not to destroy current dev and test practices, since this will mean a node that shuts down will not be able to restart until the quarantine expires.
