[jira] [Created] (KAFKA-7607) NetworkClientUtils.sendAndReceive can take a long time to return during shutdown

Bob Barrett created KAFKA-7607:
----------------------------------

             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.
