>
> KafkaConsumer.wakeup() can be used to interrupt blocking operations (e.g. in
> order to shutdown), so wakeup exceptions must get propagated to the user.
> Currently, there are several locations in the code where a wakeup exception
> could be caught and silently discarded. For example, when the rebalance
> callback is invoked, we just catch and log all exceptions. In this case, we
> also need to be careful that wakeup exceptions do not affect rebalance
> callback semantics. In particular, it is possible currently for a wakeup to
> cause onPartitionsRevoked to be invoked multiple times.
