    Description

      In the getMapOutput.jsp, tracker.mapOutputLost is called irrespective of whether the sender of the map output threw an exception or the receiver died (thereby closing the socket causing the jsp to throw an exception). Invoking the method causes the corresponding map task to fail and causes it to be rescheduled but it may be the case that the problem is at the reciever's end. Need to do a better check of where the exception was thrown.
