Brad Schoening updated CASSANDRA-16940:
---------------------------------------
Resolution: Cannot Reproduce
Status: Resolved (was: Open)
> Confusing ProtocolException msg Invalid or unsupported protocol version (4)
> ---------------------------------------------------------------------------
>
> Key: CASSANDRA-16940
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16940
> Project: Cassandra
> Issue Type: Bug
> Components: Messaging/Client
> Reporter: Brad Schoening
> Priority: Normal
>
> The following warning was seen frequently after upgrading from 3.0.15 to
> 3.11.11 in the cassandra.log:
> {noformat}
> ProtocolException: Invalid or unsupported protocol version (4); supported
> versions are (3/v3, 4/v4, 5/v5-beta){noformat}
> It is at best unclear, or maybe a bug in the code throwing this exception
> stating version '4' not supported but 4/v4 is.
> from org/apache/cassandra/transport/ProtocolVersion.java
> public static String invalidVersionMessage(int version)
> { return String.format("Invalid or unsupported protocol version (%d);
> supported versions are (%s)", version, String.join(", ",
> ProtocolVersion.supportedVersions())); }
> We later found invalid IP addresses in the system.peers table and once
> removed, this exception went away.
