Piotr Nowojski created FLINK-7343:
-------------------------------------

             Summary: Kafka010ProducerITCase instability
                 Key: FLINK-7343
                 URL: https://issues.apache.org/jira/browse/FLINK-7343
             Project: Flink
          Issue Type: Bug
          Components: Kafka Connector
            Reporter: Piotr Nowojski
            Assignee: Piotr Nowojski


As reported by [~till.rohrmann] in https://issues.apache.org/jira/browse/FLINK-6996 there seems to be a test instability with `Kafka010ProducerITCase>KafkaProducerTestBase.testOneToOneAtLeastOnceRegularSink`

It is probably related to log.flush intervals in Kafka, which delay flushing the data to files and potentially causing data loses on killing Kafka brokers in the tests.
