David Mao resolved KAFKA-16395.
-------------------------------
Resolution: Not A Bug
> Producer should refresh metadata on a socket request timeout
> ------------------------------------------------------------
>
> Key: KAFKA-16395
> URL: https://issues.apache.org/jira/browse/KAFKA-16395
> Project: Kafka
> Issue Type: Bug
> Reporter: David Mao
> Assignee: David Mao
> Priority: Critical
>
> I noticed in a set of producer logs that on a broker outage, we saw the
> following sequence of logs:
> Got error produce response with correlation id 1661616 on topic-partition
> topic-0, retrying (2147483646 attempts left). Error: REQUEST_TIMED_OUT. Error
> Message: Disconnected from node 0 due to timeout
> Got error produce response with correlation id 1662093 on topic-partition
> topic-0, retrying (2147483646 attempts left). Error: NOT_LEADER_OR_FOLLOWER
> Received invalid metadata error in produce request on partition topic-0 due
> to org.apache.kafka.common.errors.NotLeaderOrFollowerException: For requests
> intended only for the leader, this error indicates that the broker is not the
> current leader. For requests intended for any replica, this error indicates
> that the broker is not a replica of the topic partition.. Going to request
> metadata update now
> this implies we did not request metadata between our produce request
> attempts. This is a regression introduced by
> https://issues.apache.org/jira/browse/KAFKA-14317.
