----------------------------------
Summary: NetworkClientUtils.sendAndReceive can take a long time to
return during shutdown
Key: KAFKA-7607
URL: https://issues.apache.org/jira/browse/KAFKA-7607
Project: Kafka
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Bob Barrett
If a RequestSendThread is shut down while waiting on the underlying Selector to
return from a select() call, the Selector will swallow the interrupt, wake up
and return immediately. NetworkClientUtils.sendAndReceive will then potentially
re-poll the client, forcing the thread shutdown to wait for the request to
complete. We should check the thread interrupt status before re-polling the
client to prevent this delay.
