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

             Summary: Move the decoding logic from ConsumerIterator.makeNext to next
                 Key: KAFKA-1140
                 URL: https://issues.apache.org/jira/browse/KAFKA-1140
             Project: Kafka
          Issue Type: Bug
            Reporter: Guozhang Wang
            Assignee: Guozhang Wang


Usually people will write code around consumer like

while(iter.hasNext()) {
try {
  msg = iter.next()
  // do something
}
catch{
}
}

----

However, the iter.hasNext() call itself can throw exceptions due to decoding failures. It would be better to move the decoding to the next function call.
