> I think that it is silly to have tools parsing the strings that the framework builds for task ids. I propose:
> class JobId implements Writable {
>   private int;
>   ...
> }
> class TaskId extends JobId { 
>   private boolean isMap;
>   private int taskId;
>   ...
> }
> class TaskAttemptId extends TaskId {
>   private int attemptId;
>   ...
> }
> each of the classes will have a toString() method that generates the current string.
