Jason Gustafson reassigned KAFKA-1894:
--------------------------------------
Assignee: Jason Gustafson
> Avoid long or infinite blocking in the consumer
> -----------------------------------------------
>
> Key: KAFKA-1894
> URL: https://issues.apache.org/jira/browse/KAFKA-1894
> Project: Kafka
> Issue Type: Sub-task
> Components: consumer
> Reporter: Jay Kreps
> Assignee: Jason Gustafson
>
> The new consumer has a lot of loops that look something like
> {code}
> while(!isThingComplete())
> client.poll();
> {code}
> This occurs both in KafkaConsumer but also in NetworkClient.completeAll.
> These retry loops are actually mostly the behavior we want but there are
> several cases where they may cause problems:
> - In the case of a hard failure we may hang for a long time or indefinitely
> before realizing the connection is lost.
> - In the case where the cluster is malfunctioning or down we may retry
> forever.
> It would probably be better to give a timeout to these. The proposed approach
> would be to add something like retry.time.ms=60000 and only continue retrying
> for that period of time.
