Jun Rao commented on KAFKA-1733:
--------------------------------
Since this doesn't seem to be an 0.8.2 blocker, let's patch this for trunk.
> Producer.send will block indeterminately when broker is unavailable.

> Key: KAFKA-1733
> URL: https://issues.apache.org/jira/browse/KAFKA-1733
> Project: Kafka
> Issue Type: Bug
> Components: core, producer
> Reporter: Marc Chung
>
> This is a follow up to the conversation here:
> https://mail-archives.apache.org/mod_mbox/kafka-dev/201409.mbox/%3ccaog_4qymoejhkbo0n31+a-ujx0z5unsisd5wbrmn-xtx7gi...@mail.gmail.com%3E
> 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?
