Subject [jira] [Commented] (KAFKA-4020) Kafka consumer stop taking messages from kafka server
Date Fri, 26 Aug 2016 22:15:22 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-4020?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15440016#comment-15440016

Dru Panchal commented on KAFKA-4020:
------------------------------------

[~shawnhe] What stopped working? Please provide more details.
Did the consumer process crash or shutdown or did the consumer simply stop receiving messages.


If its the latter then can you provide a thread dump of the consumer process for further analysis?
See this link on how to create a thread dump: https://visualvm.java.net/threads.html

>                 Key: KAFKA-4020
>                 URL: https://issues.apache.org/jira/browse/KAFKA-4020
>             Project: Kafka
>          Issue Type: Bug
>    Affects Versions: 0.10.0.0
>            Reporter: Shawn He
>
> It feels like the similar issue of KAFKA-2978, even though I haven't verified if it is
caused by the same events. How do I check on that? 
> I have a client that works fine using kafka 0.8.2.1, and can run months without any issue.
However, after I upgraded to use kafka 0.10.0.0, it's very repeatable that the client will
work for the first 4 hours, and then stopped working. The producer side has no issue, as the
data still comes in to the kafka server. 
> I was using Java library kafka.consumer.Consumer.createJavaConsumerConnector and kafka.consumer.KafkaStream
class for the access to the kafka server.
> Any help is appreciated.
> Thanks.
