---------------------------
Resolution: Not A Bug
> Incorrect interruption invoking method used for Heartbeat thread
> -----------------------------------------------------------------
>
> Key: KAFKA-5665
> URL: https://issues.apache.org/jira/browse/KAFKA-5665
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 0.11.0.0
> Reporter: huxihx
> Assignee: huxihx
> Priority: Minor
>
> When interrupting the background heartbeat thread, `Thread.interrupted();` is
> used. Actually, `Thread.currentThread().interrupt();` should be used to
> restore the interruption status. An alternative way to solve is to remove
> `Thread.interrupted();` since HeartbeatThread extends Thread and all code
> higher up on the call stack is controlled, so we could safely swallow this
> exception. Anyway, `Thread.interrupted();` should not be used here. It's a
> test method not an action.
