Kezhu Wang created FLINK-21320:
----------------------------------
Summary: Stream from FlinkKafkaShuffle.persistentKeyBy does not
end if upstream ends
Key: FLINK-21320
URL: https://issues.apache.org/jira/browse/FLINK-21320
Project: Flink
Issue Type: Bug
Components: Connectors / Kafka
Affects Versions: 1.13.0
Reporter: Kezhu Wang
I pushed a [test
case|https://github.com/kezhuw/flink/commit/5793083c370241717c485b5663a10f72884e028b]
in my repository for evaluation, that test will hang after all input consumed.
I think we could do something(such as setting {{running}} to {{false}} upon
{{Watermark.MAX_WATERMARK}}) in
{{KafkaShuffleFetcher.partitionConsumerRecordsHandler}} to end kafka consumer.
