Neha Narkhede resolved KAFKA-626.
---------------------------------
Resolution: Fixed
Assignee: Neha Narkhede
> Produce requests dropped due to socket timeouts on get metadata requests
> ------------------------------------------------------------------------
>
> Key: KAFKA-626
> URL: https://issues.apache.org/jira/browse/KAFKA-626
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8
> Reporter: Neha Narkhede
> Assignee: Neha Narkhede
> Priority: Blocker
> Labels: bugs
>
> The setup of the test includes 2 servers with the following properties
> overridden -
> num.partitions=10
> default.replication.factor=2
> Ran producer performance to send 1000 messages to 8 topics in async mode.
> Each of the topics are auto created on the broker and default to 10
> partitions. No broker was bounced during this test.
> The producer log has the following errors -
> [2012-11-18 17:44:04,622] WARN fetching topic metadata for topics
> [Set(test1114, test1117, test1115, test1116, test1118)] from broker
