---------------------------------
Summary: AsyncKafkaConsumer hangs when NetworkClient fails
authentication
Key: KAFKA-19206
URL: https://issues.apache.org/jira/browse/KAFKA-19206
Project: Kafka
Issue Type: Bug
Components: clients, consumer
Affects Versions: 4.0.0
Reporter: Kirk True
Assignee: Kirk True
Fix For: 4.1.0
The ConsumerNetworkThread creates a new NetworkClient, which connects to and
authenticates against a broker. If the authentication fails, the NetworkClient
throws an error, causing the AsyncKafkaConsumer to close. During the consumer
close process the ConsumerNetworkThread is closed, but it throws a
NullPointerException when it attempts to use the requestManagers and/or
networkClientDelegate objects.
