> KafkaSource Stuck

> Key: GEARPUMP-122
> URL: https://issues.apache.org/jira/browse/GEARPUMP-122
> Project: Apache Gearpump
> Issue Type: Bug
> Components: kafka
> Affects Versions: 0.8.0
> Reporter: Qi Shu
> Assignee: Manu Zhang
> Fix For: 0.8.1
>
> Attachments: 2.png, screenshot-1.png
>
>
> Kafka's version is 2.10-0.8.2.0 and deployed on a cluster of 3 machines.
> Gearpump's version is 2.11-0.8.0 and deployed on local mode.
> The app running on gearpump is a java example Kafka2Kafka.
> The topic has millions of messages in It。
> After app started for a while, there were no messages received from kafka,
> but kafka console can recevie messages from that topic.
> And if I use the kafka source without offset checkpoint, then messages begin
> to flow.
> "screenshot-1.png" means app started for 7 minutes and no messages received
> from kafka source.
> "2.png" was a screen shot of JProfiler, I use JProfiler to watch the thread
> of Gearpump, and it seems the kafka source stucked when doing offset
> checkpoint.
