[jira] [Reopened] (CASSANDRA-11464) C* doesn't respond to OPTIONS request containing low protocol number

     [ https://issues.apache.org/jira/browse/CASSANDRA-11464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sandeep Tamhankar reopened CASSANDRA-11464:
-------------------------------------------

This is almost right: the only problem is that the error response is in v3/v4 form (e.g. 9 byte header). Since the node knows that we're trying to speak v1 or v2, the response needs to be of that form, too.

> Observed in Ruby and Python drivers: if you send an OPTIONS message to C* 3.4 (though I believe this goes back to 3.0) with a protocol version of 1, C* doesn't send a response to the client. If you specify a high protocol version (e.g. 5), C* does correctly respond with a protocol error.
