[GitHub] [flink] PatrickRen commented on pull request #19828: [FLINK-27762][connector/kafka] Catch WakeupException and retry KafkaConsumer invocations in split assignment

   Thanks for the review @zou-can ! Initially I was trying to fix this case from the root that `KafkaPartitionSplitReader#wakeup` should only wake up the blocking `KafkaConsumer#poll` invocation, but I realized that it's not possible to do so because Kafka consumer doesn't expose such an API. I have updated my code to add a wrapper on Kafka consumer calls that catch `WakeupException` and retry on exception.
