Brandon Williams commented on CASSANDRA-7307:
---------------------------------------------

There can be two problems here, the bigger one being a) replace will always 
refuse to replace a live a node, and b) nodes that think they need to stream 
from that node won't realize it's dead soon enough.  If overriding the initial 
value to 1s worked for you, I'm fairly certain the problem was more a) than b), 
since as we discovered earlier in the ticket there's a maximum 60s window the 
old node can be alive before that check is triggered and bails out.


> New nodes mark dead nodes as up for 10 minutes

> 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.
