[jira] [Commented] (CASSANDRA-2818) 0.8.0 is unable to participate with nodes using a _newer_ protocol version

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-2818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13055775#comment-13055775 ] 

Jonathan Ellis commented on CASSANDRA-2818:
-------------------------------------------

bq. It shuts the connection down slightly too aggressively, causing an exception on the remote side before setVersion gets called

I can see that the initiating side could get pissed that the target closes the socket uncleanly -- what I don't get is how a sleep could make a difference.  Is it on the reconnect?  In which case the sleep is going to be fragile with a bigger cluster, since we depend on gossip to spread the version info.

Do you have a sample stacktrace?

> When a 0.8.1 node tries to join a 0.8.0 ring, we see an endless supply of these in system.log:
