-------------------------------------
Summary: Shutdown of KafkaProducer causes confusing log message
Key: FLINK-9390
URL: https://issues.apache.org/jira/browse/FLINK-9390
Project: Flink
Issue Type: Bug
Components: Kafka Connector
Affects Versions: 1.5.0, 1.6.0
Reporter: Stefan Richter
I found some logged exceptions in a user log that occurred during shutdown in
the context of the Kafka Producer. Those exceptions are most certainly not a
real problem, but can be confusing to users, so maybe we can get rid of them.
