             Summary: Fix flaky python-tests due to connection getting closed
                 Key: CASSANDRA-17594
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17594
             Project: Cassandra
          Issue Type: Bug
          Components: Test/dtest/python
            Reporter: David Capwell
            Assignee: David Capwell


We log unknown exceptions at the networking level, which includes case where the remote side closes the connection (such as the cases caused by shutting down), depending on how quickly the instances shutdown, this could cause python-dtest to fail for random tests with a message such as

{code}
Unexpected error found in node logs (see stdout for full details). Errors: [WARN  [epollEventLoopGroup-5-9] 2022-05-03T16:47:03,800 ExceptionHandlers.java:134 - Unknown exception in client networking
io.netty.channel.unix.Errors$NativeIoException: writeAddress(..) failed: Connection reset by peer, WARN  [epollEventLoopGroup-5-9] 2022-05-03T16:47:03,800 ExceptionHandlers.java:134 - Unknown exception in client networking
io.netty.channel.unix.Errors$NativeIoException: writeAddress(..) failed: Connection reset by peer]
