> Node restart during joining sets protocol version to V3
> -------------------------------------------------------
>
> Key: CASSANDRA-16518
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16518
> Project: Cassandra
> Issue Type: Bug
> Components: Messaging/Client
> Reporter: Joseph Clay
> Assignee: Stefan Miklosovic
> Priority: Normal
> Fix For: 3.11.x
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> While joining nodes to a cluster, an old node crashed. The old node was
> recovered however clients (datastax java) refused to connect to it.
> The driver error:
> {noformat}
> Detected added or restarted Cassandra host /<ip>:<port> but ignoring it since
> it does not support the version V4 of the native protocol which is currently
> in use.{noformat}
> In the recovered node cassandra logs:
> {noformat}
> INFO o.a.c.transport.ConfiguredLimit Detected peers which do not fully
> support protocol V4. Capping max negotiable version to V3{noformat}
> I confirmed that ALL the nodes in the cluster, joining or otherwise, were
> apache-cassandra-3.11.6 so that error message was rather confusing.
> Eventually after digging through the code we got to the bottom of the issue:
> https://issues.apache.org/jira/browse/CASSANDRA-15193 adds a check for node
> version, which reverts the protocol version to V3 if any peer fails the
> version check. Joining nodes have NULL for their version in the peers table,
> which fails the version check.
