------------------------------------

             Summary: Improve error reporting in the Sender for request types
                 Key: KAFKA-1256
                 URL: https://issues.apache.org/jira/browse/KAFKA-1256
             Project: Kafka
          Issue Type: Sub-task
          Components: producer 
    Affects Versions: 0.9.0
            Reporter: Neha Narkhede
            Priority: Critical


I ran a test using the new mirror maker to copy one large topic and ran into 
the following error in the producer -

java.lang.IllegalStateException: Attempt to begin a send operation with prior 
send operation still in progress.
