gaborgsomogyi opened a new pull request #28871: URL: https://github.com/apache/spark/pull/28871
### What changes were proposed in this pull request? Spark uses an old and deprecated API named `KafkaConsumer.poll(long)` which never returns and stays in live lock if metadata is not updated (for instance when broker disappears at consumer creation). Please see [Kafka documentation](https://kafka.apache.org/25/javadoc/org/apache/kafka/clients/consumer/KafkaConsumer.html#poll-long-) and [standalone test application](https://github.com/gaborgsomogyi/kafka-get-assignment) for further details. In this PR I've applied the new `KafkaConsumer.poll(Duration)` API on executor side. Please note driver side still uses the old API which will be fixed in SPARK-32032. ### Why are the changes needed? Infinite wait in `KafkaConsumer.poll(long)`. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing unit tests. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
