Rick Branson commented on CASSANDRA-5565:
-----------------------------------------
I came to the same conclusion (operator error), and clearly I was wrong about
it being attributed to CASSANDRA-5167, but I'm also trying to think of
scenarios in which one would actually want this behavior. It seems on the
surface to be technically trivial to reject nodes that attempt to do this and
prevent a lot of headache.
> Peer entry drops from system table silently when bootstrapping a node with an
> existing IP.

> URL: https://issues.apache.org/jira/browse/CASSANDRA-5565
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.2.4
> Reporter: Rick Branson
> Assignee: Brandon Williams

> It looks like CASSANDRA-5167 introduced a bit of a regression. I needed to
> rebuild the data on a malfunctioning node by rebootstrapping it. I did this
> by cleaning the host and restarting Cassandra. My plan was to remove the old
> hostID once it had successfully bootstrapped.
> No errors were encountered, but the old host ID of the node before the wipe
> was completely dropped from the peers table because they had the same IP
> address, and therefore the data ranges were moved around. This resulted in a
> large number of CL.ONE reads coming back empty.
> There might be a better approach to this rebootstrap process, but it seems
> like it's dangerous to just drop the peer from the table, especially without
> any kind of log message.
