> This issue was originally reported by a Samza developer. I've included an
> exchange of mine with Chris Riccomini. I'm trying to reproduce the problem on
> my dev setup.
> From: criccomi
> Hey all,
> Samza's BrokerProxy [1] threads appear to be wedging randomly when we try to
> interrupt its fetcher thread. I noticed that SimpleConsumer.scala catches
> Throwable in its sendRequest method [2]. I'm wondering: if
> blockingChannel.send/receive throws a ClosedByInterruptException
> when the thread is interrupted, what happens? It looks like sendRequest will
> catch the exception (which I
> think clears the thread's interrupted flag), and then retries the send. If
> the send succeeds on the retry, I think that the ClosedByInterruptException
> exception is effectively swallowed, and the BrokerProxy will continue
> fetching messages as though its thread was never interrupted.
> Am I misunderstanding how things work?
> Cheers,
> Chris
