> As far as I know spout methods are not called concurrently by Storm. When the
> new Kafka spout closes or deactivates, the closing thread calls
> KafkaConsumer.wakeup. If there are uncommitted offsets and the spout is in
> manual commit mode, it then tries to commit offsets. Since there are no other
> threads concurrently interacting with the spout, the call to
> KafkaConsumer.commitSync will end up throwing WakeupException. This is
> because the behavior of wakeup is to cause the next blocking call to throw
> WakeupException if there are no other threads blocking on the consumer when
> wakeup is called.
> The call to wakeup should be removed, since it does nothing if there are no
> offsets to commit, and causes an uncaught exception if there are.
