KafkaConsumer.poll(long) pauses indefinitely

[William Grim]

Hi,

I'm noticing that when we have a thread that comes up and calls
KafkaConsumer.poll(long), it will pause for a much longer time than our 1s
timeout.  It looks like this is probably happening when kafka gets down to
calling ConsumerNetworkClient.epollWait after calling
ConsumerNetworkClient.poll(Future), because that API seems to pass
Long.MAX_VALUE as the timeout to the low-level libs.

So, my question is if this is a known bug?  I couldn't find anything about
it, but it seems like if I start generating random traffic to that topic,
the timeout resolves sooner but not much sooner than now.

Thanks!
