Jacek Lewandowski created CASSANDRA-19218:
---------------------------------------------
Summary: NettyStreamingConnectionFactory lacks handling of
outcomes other than success
Key: CASSANDRA-19218
URL: https://issues.apache.org/jira/browse/CASSANDRA-19218
Project: Cassandra
Issue Type: Bug
Components: Legacy/Streaming and Messaging
Reporter: Jacek Lewandowski
This is not a critical issue, but the errors thrown when we try to connect with
incompatible messaging version (for example from an sstable loader) are odd. We
get weird looking class cast exceptions like this:
{format}
Session peer /127.0.0.1:7012 Failed because of an unknown exception
java.lang.ClassCastException: class
org.apache.cassandra.net.OutboundConnectionInitiator$Result$Incompatible cannot
be cast to class
org.apache.cassandra.net.OutboundConnectionInitiator$Result$Success
(org.apache.cassandra.net.OutboundConnectionInitiator$Result$Incompatible and
org.apache.cassandra.net.OutboundConnectionInitiator$Result$Success are in
unnamed module of loader 'app')
org.apache.cassandra.net.OutboundConnectionInitiator$Result.success(OutboundConnectionInitiator.java:520)
org.apache.cassandra.streaming.async.NettyStreamingConnectionFactory.connect(NettyStreamingConnectionFactory.java:68)
{format}
We should probably handle that somehow and error out with a reasonable message,
which at least would prove that we consciously refuse to connect.
