-----------------------------------------------------------------------
You're right, RING_DELAY has no effect when replacing because we only sleep for
load dissemination, which is 60s. So the only workaround left is to override
the FD initial value. Fixed the typo in 4e67631ef8.

> Project: Cassandra
> Issue Type: Bug
> Reporter: Richard Low
> Assignee: Brandon Williams

>
> When doing a node replacement when other nodes are down we see the down nodes
> marked as up for about 10 minutes. This means requests are routed to the dead
> nodes causing timeouts. It also means replacing a node when multiple nodes
> from a replica set is extremely difficult - the node usually tries to stream
> from a dead node and the replacement fails.
> This isn't limited to host replacement. I did a simple test:
> 1. Create a 2 node cluster
> 2. Kill node 2
> 3. Start a 3rd node with a unique token (I used auto_bootstrap=false but I
> don't think this is significant)
> The 3rd node lists node 2 (127.0.0.2) as up for almost 10 minutes:
> {code}
> INFO [main] 2014-05-27 14:28:24,753 CassandraDaemon.java (line 119) Logging
> initialized
> INFO [GossipStage:1] 2014-05-27 14:28:31,492 Gossiper.java (line 843) Node
> /127.0.0.2 is now part of the cluster
> INFO [GossipStage:1] 2014-05-27 14:28:31,495 Gossiper.java (line 809)
> InetAddress /127.0.0.2 is now UP
> INFO [GossipTasks:1] 2014-05-27 14:37:44,526 Gossiper.java (line 823)
> InetAddress /127.0.0.2 is now DOWN
> {code}
> I reproduced on 1.2.15 and 1.2.16.
