Qingsheng Ren commented on FLINK-13733:
---------------------------------------
Hello everyone, I ran this test case locally with TRACE level log. Records are
indeed produced to and logged by Kafka, but the consumer was just closed after
it sends consume request and before getting response from the broker. I think
we can extend the timeout value of kafkaConsumer.poll() method in assertRecord
a little bit. I'll create a PR for this.
