[jira] [Commented] (CASSANDRA-9289) Recover from unknown table when deserializing internode messages

    [ https://issues.apache.org/jira/browse/CASSANDRA-9289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15681453#comment-15681453 ] 

ZhaoYang commented on CASSANDRA-9289:
-------------------------------------

This fix is to wrap message in-stream with TrackedDataInputPlus, if caught UnknownCFException, skip the remaining bytes in this message. TCP won't be closed and it will remain connected for other messages.

> As discussed in CASSANDRA-9136, it would be nice to gracefully recover from seeing an unknown table in a message from another node.  Currently, we close the connection and reconnect, which can cause other concurrent queries to fail.
