Shikhar Bhushan commented on KAFKA-4375:
----------------------------------------
Good to have a report of this being a problem, I opened KAFKA-4356 recently
after chancing on the code. It seems like an oversight rather than by design.
> Kafka consumer may swallow some interrupts meant for the calling thread
> -----------------------------------------------------------------------

> Key: KAFKA-4375
> URL: https://issues.apache.org/jira/browse/KAFKA-4375
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Reporter: Stig Rohde Døssing
>
> Apache Storm has added a new data source ("spout") based on the Kafka 0.9
> consumer. Storm interacts with the consumer by having one thread per spout
> instance loop calls to poll/commitSync etc. When Storm shuts down, another
> thread indicates that the looping threads should shut down by interrupting
> them, and joining them.
> If one of the looping threads happen to be interrupted while executing
> certain sleeps in some consumer methods (commitSync and committed at least),
> the interrupt can be lost because they contain a call to SystemTime.sleep,
> which swallows the interrupt.
> Is this behavior by design, or can SystemTime be changed to reset the thread
> interrupt flag when catching an InterruptedException?
> I haven't checked the rest of the client code, so it's possible that this is
> an issue in other parts of the code too.
