Paulo Motta commented on CASSANDRA-16213:
-----------------------------------------
Overall I like the proposed approach, I would just limit propagating state
about the downed host *only* during shadow gossip response (and *not* during
normal gossip) to limit the potential surface area of this change. I think we
should extract the shadow gossip response from {{examineGossiper}} to make this
cleaner.
A natural consequence of this is that we will never need to handle the state
"UNKNOWN" on {{StorageService.onChange}} so it would be nice to add an
assertion there if we ever get a notification about this change on a live node.
I like the tests but I'm not very familiar with in-jvm dtest infrastructure so
it would be nice to get a pair of eyes on that to make sure the framework
changes look good.

> Key: CASSANDRA-16213
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16213
> Project: Cassandra
> Issue Type: Bug
> Components: Cluster/Gossip, Cluster/Membership
> Reporter: David Capwell
> Assignee: David Capwell
> Priority: Normal
> Fix For: 4.0-beta
>
>
> We see this exception around nodes crashing and trying to do a host
> replacement; this error appears to be correlated around multiple node
> failures.
> A simplified case to trigger this is the following
> *) Have a N node cluster
> *) Shutdown all N nodes
> *) Bring up N-1 nodes (at least 1 seed, else replace seed)
> *) Host replace the N-1th node -> this will fail with the above
> The reason this happens is that the N-1th node isn’t gossiping anymore, and
> the existing nodes do not have its details in gossip (but have the details in
> the peers table), so the host replacement fails as the node isn’t known in
> gossip.
> This affects all versions (tested 3.0 and trunk, assume 2.2 as well)
