[jira] [Comment Edited] (KAFKA-4) Confusing Error mesage from producer when no kafka brokers are available

["Sönke Liebau (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-4?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16254975#comment-16254975 ]

------------------------------------------------------------

Current error message when no broker is available is:

{code}
WARN Connection to node -1 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)
{code}

This message was introduced by KAFKA-5179, so I think it is save to say that we can close this ticket as well with the same fix version. Before that there were other error messages that also improved upon this message, but I don't think we need to provide the entire history here..
