> 1. A mechanism should be provided where the user can specify that there is a error in
his custom script. The whole job/query should be 
> stopped at that time. 
> 2. It would be useful if the offending row on which the script failed can be provided
> 3. It would be very useful if on a rerun, only that mapper/reducer runs so that it is
easy to debug the problem.
> The above 3 can be split into different jiras also.
