Chia-Ping Tsai updated KAFKA-18160:
-----------------------------------
Summary: Interrupting or waking up onPartitionsAssigned in AsyncConsumer
can cause the ConsumerRebalanceListenerCallbackCompletedEvent to be skipped
(was: Interrupting or waking up onPartitionsAssigned in AsyncConsumer can cause
the ConsumerRebalanceListenerCallbackCompletedEvent to be skipped, potentially
leading to corrupted added partitions)

> I noticed this issue when testing KAFKA-17962. It includes two bugs listed
> below.
> *ConsumerRebalanceListenerCallbackCompletedEvent is skipped*
> `invokeRebalanceCallbacks`could throw WakeupException/InterruptException [0]
> and they are NOT handled. Hence, the event
> `ConsumerRebalanceListenerCallbackCompletedEvent` is NOT sent to background
> thread.
> *Solution*: We should use try-catch blocks to propagate both
> InterruptedException and WakeupException to the background thread.
> the second issue is expected behavior, so please ignore it :)
> -*corrupted added partitions*-
> -In the next iteration of invokeRebalanceCallbacks, non-fetchable assigned
> partitions are treated as owned partitions [1]. This results in "empty"
> partitions being passed to the listener, meaning that the listener never
> receives the correctly added partitions after the first execution fails.
> Consequently, this causes the test_pause_and_resume_sink (KAFKA-17962) to
> become unstable when using AsyncConsumer.-
> -*Solution*: We should add only partitions where pendingOnAssignedCallback is
> false to the owned partitions.-
