-------------------------------------
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`
https://travis-ci.org/tillrohrmann/flink/jobs/258538641
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.
