Sagar Sadashiv Patwardhan commented on KAFKA-4739: -------------------------------------------------- [~hachikuji] [~huxi_2b] Thanks for getting back to us. We really appreciate your help! :) It is interesting to see that between L151 and L178 of https://gist.github.com/neoeahit/3a0a5027bc3499b85cb888918faac2a3 kafka client does not send any requests to the broker. We get successful heartbeat responses from the coordinator, but we still timeout for some reason after ~40 secs(default request.timeout.ms). I have not read the client code in detail(may be I should), but if the heartbeats are successful, then why are we timing out? Also, the request timeout is 500 msec per documentation, so how is this timeout related to request.timeout.ms(40 secs). > KafkaConsumer poll going into an infinite loop > ---------------------------------------------- > > Key: KAFKA-4739 > URL: https://issues.apache.org/jira/browse/KAFKA-4739 > Project: Kafka > Issue Type: Bug > Components: consumer > Affects Versions: 0.9.0.1 > Reporter: Vipul Singh > > We are seeing an issue with our kafka consumer where it seems to go into an > infinite loop while polling, trying to fetch data from kafka. We are seeing > the heartbeat requests on the broker from the consumer, but nothing else from > the kafka consumer. > We enabled debug level logging on the consumer, and see these logs: > https://gist.github.com/neoeahit/757bff7acdea62656f065f4dcb8974b4 > And this just goes on. The way we have been able to replicate this issue, is > by restarting the process in multiple successions. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
