[jira] [Created] (KAFKA-15867) Should ConsumerNetworkThread wrap the exception and notify the polling thread?

Philip Nee created KAFKA-15867:
----------------------------------

             Summary: Should ConsumerNetworkThread wrap the exception and notify the polling thread?
                 Key: KAFKA-15867
                 URL: https://issues.apache.org/jira/browse/KAFKA-15867
             Project: Kafka
          Issue Type: Bug
          Components: consumer
            Reporter: Philip Nee


The ConsumerNetworkThread runs a tight loop infinitely.  However, when encountering an unexpected exception, it logs an error and continues.

 

I think this might not be ideal because user can run blind for a long time before discovering there's something wrong with the code; so I believe we should propagate the throwable back to the polling thread.
