Guozhang Wang commented on KAFKA-1461: -------------------------------------- I did not realize this ticket exist, and created the same one here (KAFKA-1629). It has some more detailed explanation of the issue though. > Replica fetcher thread does not implement any back-off behavior > --------------------------------------------------------------- > > Key: KAFKA-1461 > URL: https://issues.apache.org/jira/browse/KAFKA-1461 > Project: Kafka > Issue Type: Improvement > Components: replication > Affects Versions: 0.8.1.1 > Reporter: Sam Meder > Assignee: nicu marasoiu > Labels: newbie++ > > The current replica fetcher thread will retry in a tight loop if any error > occurs during the fetch call. For example, we've seen cases where the fetch > continuously throws a connection refused exception leading to several replica > fetcher threads that spin in a pretty tight loop. > To a much lesser degree this is also an issue in the consumer fetcher thread, > although the fact that erroring partitions are removed so a leader can be > re-discovered helps some. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
