Subject [jira] [Commented] (KAFKA-1733) Producer.send will block indeterminately when broker is unavailable.
Date Tue, 04 Nov 2014 15:39:34 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-1733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14196240#comment-14196240

R. Tyler Croy commented on KAFKA-1733:

Thanks a lot [~junrao]! As somebody not terribly familiar with the Kafka release process,
is there a document you could point me to that describes the release cadence or when we might
expect a release to be cut with this change?

>             Project: Kafka
>          Issue Type: Bug
>          Components: core, producer 
>            Reporter: Marc Chung
>            Assignee: Marc Chung
>             Fix For: 0.8.3

> This is a follow up to the conversation here:

> During ClientUtils.fetchTopicMetadata, if the broker is unavailable, socket.connect will
block indeterminately. Any retry policy (message.send.max.retries) further increases the time
spent waiting for the socket to connect.
> The root fix is to add a connection timeout value to the BlockingChannel's socket configuration,
like so:
> {noformat}
> -channel.socket.connect(new InetSocketAddress(host, port))
> +channel.socket.connect(new InetSocketAddress(host, port), connectTimeoutMs)
> {noformat}
> The simplest thing to do here would be to have a constant, default value that would be
applied to every socket configuration. 
> Is that acceptable?
