------------------------------------
Summary: Calling KafkaProducer.close() from multiple threads may
cause spurious error
Key: KAFKA-4856
URL: https://issues.apache.org/jira/browse/KAFKA-4856
Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 0.10.2.0, 0.10.0.0, 0.9.0.0
Reporter: Xavier Léauté
Priority: Minor
Calling KafkaProducer.close() from multiple threads simultaneously may cause
the following harmless error message to be logged. There appears to be a
race-condition in AppInfoParser.unregisterAppInfo that we don't guard against.
{{WARN Error unregistering AppInfo mbean
